Patch 1.0.0.112

Jarvan:
Cataclysm:

• Poppy's Heroic Charge pushes people right out of it
• Janna and anyone with Ghost can run right out of the ring

Patch 1.0.0.111

Maokai:
Sappling Toss:

• It will blow up on the first enemy it hits. This means that you can drop a ward between you and the sappling while running away to make it prematurely detonate.

Twisted Advance:

• Odd behavior when you use the skill on a target that dies. Sometimes it will burn the cooldown and mana while other times it won't depending on how soon or late you hit the skill. When I tested this, I am sure I wasn't simply clicking too late on the target because Maokai still started the animation of sinking into the ground.

General:

• Shields are on a first in first out system. This means the shield that was applied first will take damage first. You can use this to your advantage with Black Shield by putting it on your carry after Janna or Karma shield to ensure that you get the most CC immunity. 

Patch 1.0.0.110

Anivia:
Flash Frost and Glacial Storm:

• Since these spells have the same chilled effect, if you first cast Glacial Storm and then double hit with Flash Frost, the game will forget the first source of chilled and apply Glacial Storm chilled effect a second time.

Cho'Gath:
Feast:

• Gives a stack on feast if your target was below the threshold but was shielded. This results in the target potentially not dying because the shield absorbed the damage, but you still gaining HP.

Cassiopeia:

Twin Fang

• Range is 550 instead of 700
• There seems to be a global issue with ranges being inconsistent. I believe that auto attacks and spells are using 2 separate metrics for range. I've noticed that Annie, with a 625 attack range, out ranges 700 cast range spells.

Karma:

Spirit Bond:

• Champions with dash abilities are able to dash through the chain without being slowed.

Irelia:

Transcendent Blades:

• Actual cooldown and tooltip don't match when you have CDR.

Renekton:

Dice and Slice:

• You are able to dash through Veigar wall and Karthus wall without being stunned/slowed.
• Does not factor in bonus armor when calculating the percentage of armor being reduced.

Urgot:

Noxian Corrosive Charge:

• Currently able to drop armor into negatives if they use a defensive steroid skill.

General:

• If you go stealth under an enemy turret, the turret will de-agro you even though the turret can still see you. Currently trying to figure out a way to abuse this with Akali and her smoke bomb. Could mean that I can turret dive and not have the turret target me.

Patch 1.0.0.109

Caitlyn:
Ace in the Hole:

• Still can be fogged juked before the gear particle gives you vision of the target

Gangplank:
Raise Morale:

• The skill spell vamps.

LeBlanc:
Distortion:

• Currently the damage breaks Veil  and still deals damage. This allows Sigil of Silence's mark to be popped by using Distortion through a spell shield.

Trundle:
Pillar of Filth:

• Currently draws tower agro because, like Anivia's wall, it deals one true damage.

Renekton:
General:

• Does not gain Fury while hitting structures. Might be intended.

Items:
Guardian Angel:

• Certain abilities persist through "death"  by Guardian Angel (Mundo Ult, Renekton Ult, etc)

General:

• Critical chance has all kinds of weird nonsense going on with it. At high percentages there seems to be a lot less crits.
• I've compiled a list of all of the on-hit abilities in the game and their behavior with spell shields and Pantheon's Aegis. For the cells that you can't see the entire entry, click the cell and the full entry will show up at the top.
• On-hit Abilites
• Twisted Fate Stacked Deck and Pick a Card

Patch 1.0.0.108

Caitlyn:

Piltover Peacemaker:

• Particle extends farther than the hitbox
• Particle sometimes doesn't show

Yordle Trap:

• Not revealing fog properly when the trap is initially cast

90 Calibur Net:

• Can be cast while rooted but does not propel you. Should be consistent with other self propelling spells in the game and be completely disabled. (Not really a bug, more of a design choice)
• You can cast Piltover Peacemaker and yordle trap while being knocked back by 90 Calibur Net but cannot channel your ultimate. (Again another design choice issue)

Ace in the Hole:

• Can be blocked by Pantheon
• Tooltip says nothing about on-hit effects even though it does
• (Unconfirmed) Sheen procs are consumed but don't deal bonus damage
• Crits but doesn't deal bonus damage

Evelynn:

Shadow Walk:

• Breaks her stealth if she uses Death Fire's Grasp but does not stun.

Gangplank:

Raise Morale:

• You gain 2 gold off of TF's passive, Loaded Dice, when you use this

Irelia:

Equilibrium Strike:

• Seems to have less range than intended. In the patch notes it said the range was changed to 425. However, Bilgewater Cutlass currently outranges EQ Strike when the tooltip says it has a range of 400. In this case, either Cutlass' range is incorrect, EQ Strike's range is incorrect or both.

LeBlanc:

Mirror Image:

• Clone shows up as a normal red dot on the minimap (similar to minions) instead of the champion icon

Mordekaiser:
General:

• If you die with shields on, your shield does not degen.

Nidalee:

Bushwack:

• Tooltip for scaling is incorrect for higher levels of the skill. I think past level 3 the numbers are off
• The AR/MR reduction amount is incorrect. I think it's not taking into effect bonus ar/mr
• Not revealing fog properly when the trap is initially cast

Cougar Form:

• Skills are sometimes dealing 0 damage. Not sure what circumstances this is the case.

Pantheon:

Grand Skyfall: 

• Still not showing the circle to enemies in some situations

Shaco:

Hallucinate:

• Clone currently steals buff if it gets the last hit
• Clone shows up as a normal red dot on the minimap (similar to minions) instead of the champion icon.

Trundle:

Agony:

• Currently able to drop a champ to negative ar/mr values if they have a skill that increases their ar/mr value. Here's an example:

1. Master Yi uses meditate to increase his ar/mr to 400/400.
2. Trundle uses level 3 agony which steals a total of 50% of your MR over the 6 seconds thus stealing a total of 200/200 of Master yi's ar/mr
3. Meditate ends before agony ends thus putting yi at his base value of 80ar/30mr (or whatever)
4. But agony is still stealing that initial value of 200 so by the time the skill ends, yi has -120ar/-170mr.

Udyr

General:

• Udyr's first skill of the game that he uses has no cooldown. (Probably an issue with going from neutral form into one of the animal forms)

Tiger Stance:

• On hit magic damage effect is "absorbed" by hitting a turret even though it deals no bonus damage.

Phoenix Stance:

• The timing of the flame pulse animation does not match up with the damage. Timing of the flame pulses behaves something like this: 1....2...3..4.5

Items:

Bilgewater Cutlass and Hextech Gunblade:

• Their actives have the same slow effect. Meaning that if you use both items on one target, they will still be slowed for 50% instead of 75%. Either the items' actives' effect need to be distinct from one another or the items need to share the same active. (Thus putting both on cooldown when you use one of them like if you had 2 zhonyas)

Potions:

• Requires you to target yourself to consume sometimes. I think the cause of this may be related to the ward bug.

Wards:

• There is currently a gamebreaking bug where under certain conditions, a champion is unable to drop a ward. This happened to me in game today. I was playing Trundle with Lanturn, Brutalizer, Triforce and Merc Treads. I could not drop the pink ward I had in my inventory. Going to try to reproduce the bug in the next few days. Teams were
• Trundle
• Annie
• Malphite
• Lux
• Garen

• Shen
• Sion
• Vlad
• MF
• Nunu    

Summoner's Rift

• Ancient Golem on blue team has the small minions aligned in such a way that its easier to hit with line AoEs standing from the safety of the brush. Purple's Ancient Golem does not have small minions lined up this way. This gives an extremely slight advantage to characters who have line AoEs on blue team.
• Baron can kill wards.
• Dragon does not target properly when he is pulled into the wall by Blitzcrank
• The flowers in the river on the Autumn map are on the wrong layer. They appear over any champion that walks over them instead of under them.

PvP.net:

Chat:

• Open up a chat room with the same name as someone you're currently talking to. Let the bugs flow like water. Open a public chat room while doing this for more hilarity.

Website:

Items:

• Wit's End tooltip needs to be updated to state it deals magic damage.
