Any advice for fighter build? What should I focus on?
Just lvl 11 so far but I love this game
Cyclone Masher
Tempest Edge
Rebuke
Cover Allies
Shield Tactics
Cyclone Masher lets you hang in the air. The more points you put into it, the larger the slash range, and the slower you fall (meaning more damage on target). Combine this with jumps and evades and you can stay off the ground for a LONG time. Excellent anti-air.
Tempest Edge is a flurry of slashes on the ground, and the more points you put into it the more damage it does. IIRC putting more points boosts the time it lasts, which you definitely want.
Both Cyclone Masher and Tempest Edge will be your go-to offensive abilities.
Cover Allies is mandatory (IMO) on any Fighter. At level 1 it boosts your attack 30% when you guard an attack. At level 2 it's coverage range (to defend your teammates)
jumps and the attack boost you get is 70% now. Level 3 creates a large shielded area and doubles your attack stat. Cover Allies + Tempest Edge/Cyclone Masher = Beautiful
Reflex Guard is incredible. It auto-guards an incoming attack, negating damage. At max level it blocks 50% of attacks. What's even
more impressive is that
COVER ALLIES' ATTACK BOOST ACTIVATES EVEN WITH AUTO-GUARDS. That means Fighter gets a free attack boost on a regular basis. Max this and Cover Allies ASAP.
The last one is Shield Tactics and should not be overlooked. It makes you capable of guarding against really strong attacks or lots of incoming blows without being blasted back (and losing your sword). Being able to block a boss's attack and punish feels so damn good.
Those are the 5 Fighter Skills that I consider must-haves.
Some others to deserve lots of love are Judgment (falling thrust into the ground with shockwave) and Rebuke (strengthens the power of Megasmash and any other shockwaves the Fighter produces). Boosting Judgment makes it do more damage and increases the shockwave size. Boosting Rebuke makes the shockwaves stronger.
Being able to jump over a mob and drop down onto them like a bomb feels great.
