I wanted to describe Staff abilities in my own words, in case it helps newer players understand how they function more easily. If you're not new to the skill, you can probably skip this whole section or most of it.
Hogan
Heed the Stick - "tanking" ability. increases your aggro. you can mod it to mitigate 24 damage for 10 seconds. Thats enough time to fire off the skill again and always have 24 mitigation up.
Headcracker (Nice) - damage ability. If modded to be the end stage of the Suppression Stun combo, this will stun your single target. can also reduce the targets rage.
Phoenix Strike (Epic) - newly added this year. 60 second cooldown unmodded. moddable to increase Fire dmg for some seconds, heal you, decrease its own cooldown, buff your Major Healing abilities, and trigger vulnerability.
Wombat
Suppress - Strongest AOE dmg dealer and rage reduction. beginning of Suppression Stun combo (Suppress+AnyMelee+AnyMelee+Headcracker). moddable to deal more dmg and reduce more rage.
Furlak
Pinning Slash - Shares a cooldown with Pin. Deals some initial dmg and then some trauma over time. Meant to be used as part of the Staff/Unarmed skill combo that Citan has been working on. This version of pin doesn't root the target for multiple seconds. It stuns them momentarily.
Level Up
Double Hit (Core) - great dmg dealer that can reduce cooldown on Headcracker and increase dmg the next crushing attack you do.
Deflective Spin - reduces all types of incoming dmg by 40% for 8 seconds! amazing. can be modded to restore health over time, immediately, and restore power after a delay. Spam it!
Blocking Stance (Survival Utility) - makes you immune to piercing, crushing, and slashing damage for 10 sec. costs no power at higher ranks. can be modded to restore power immediately, increase dmg to Mentalism attacks, and increase healing amount of First Aid ability. This means you can save money and use only Good kits and still get the heal of an Amazing kit. They are expensive.
Smash (Basic) - pretty straightforward Combat Refresh ability. Pretty moddable but nothing very exciting.
Safe Fall (Sidebar) - extremely useful ability which allows you to take zero fall damage. useful if you don't have a flight form like me.
Pin (Signature Debuff) - roots the target in place. modded, this ability can have the widest array of effects such as -40% dmg to target, healing, reduce rage, increase dmg of Core attacks, etc.
Lunge - a light hit that can be modded to do AOE dmg, restore armor, and knockback.
Redirect - hits target, knocks them back, and reduces your taunt to them so they attack someone else. very moddable (-taunt, +%dmg, trauma dmg, more rage reduction).
Strategic Thrust - piercing dmg. deals more dmg to vulnerable targets.
