Here I found some Chanter status effects information of Aion from other site, hope it could draw your attention and help you some !

Heavens judgement: chance of short duration stun, usable at range
parry strike: long cooldown stun
xxx lock: short cooldown racial skill with chance of stun, usable at range
all useful for sneaking in a heal or interupting a skill/chain

Heroic strike: long cooldown knockback on a stunned target, requires stigma.
The status effect list leads me to believe knockback is a type of knockdown, so aion kina be handy for burst with the combo, parry strike, heroic strike, resonance haze.

Condemnation: slows targets attack speed
crush lock: reduces phys def by 5%
resonance lock: 8 second ground snare
Our real snare and on a long 24 second cooldown only, it is difference about timing this in aion kina in a kill and stories of fish big that just got away. it also has a chance to trigger a stronger pure damage ability.

Spell of trap: short duration ranged root with snare, requires stigma of dubious use according to reports from china, seems handy on paper but with oldingcomment .

Shooting starr blow: 4 second flight snare and phys def debuff
incandescent blow: phys def debuff
pentacle shock: knockdown
The phys def debuffs are minor but the snare great vs rdps classes who often take to the air, the knockdown can lead to resonance haze one of our best dps abilities.

We also have a few pure dps abilites like resonance haze which deals high damage to a target who has been aion kina down, and when you use resonance lock thunderbolt lock which has a chance to trigger.
