Riddle of fire: make it 10% damage increase and thats it. No slowing us down.

Riddle of earth: Make it give us one stack of GL upon getting hit (works only one time obviously). If you were at 3 already, cool, it refresh the timer. If you loose GL during a very long phase transition (Lakshmi for ex), with this new effet you get at least ONE stack back. Better than nothing.

Steal peak: Make it act like Empyreal arrow from bard, give automaticaly a chakra by using it.

Fire tackle: Make it do like a small explosion of fire or something that deal AOE damage in a small radius, like 5y or maybe 10y

Earth tackle: Make it do a small earthquake or shockwave that is a stun AOE in a small radius, this would act like HOLY from WHM and be far more usefull (as if the actual Earth tackle was usefull lol...).

Tornado kick: Maybe make it stronger so that its worth using again?
