Exceed + Life Sap

[Stereo]

Descriptions:
Life Sap (max): 100% chance to recover 5% hp on hit
Exceed: Life Sap -1% for every 20 Exceed Overload cap and 2 Overload stacks

Interpretations:
Life Sap: 100% chance to recover 5% hp on an attack
Exceed 20 Exceed Overload cap, Life Sap -1% for 2 Overload stacks.


Tests using regular attacks (since they don't generate Exceed):
1 Exceed: 5% hp regen
5 exceed: 3% hp regen
6 exceed: 2% hp regen
8, 9 exceed: 1% hp regen
10+ exceed: 1 hp regen
So like it says, -1% for every 2 stacks. 0,1 = 5%, 2,3 = 4%, 4,5 = 3%, 6,7 = 2%, 8,9 = 1%, 10+ = 0%.

Tests using Demon Strike (which is annoying cause it generates Exceed):
-1% to -3% hp loss with 10+ exceed (consistently 3% at 20 exceed, not sure on where it transitions)


To do more detailed tests I need to relog and disable my Aran card, that +600/+1200 hp is severely getting in the way :|

also it will only cost hp to cast the skill if you actually hit the monster

Still increases exceed counter even if the skill doesnt hit mobs or use HP. Also, i noticed something while training, if a skill uses 2% HP, and you have less than 2% HP, the skill will still be used, but you don't lose any HP.
