Some archers feel the best way to fight a foe is with speed and accuracy. The Arbalest knows that the best way to fight is to wear lots of heavy metal and shoot lots of heavy metal with other pieces of heavy metal attached to it. Using the heavily modified bow-like weapons that earned them their names, Arbalests can fire other weapons such as spears and axes like ammunition and retrieve them with ease - after dealing heavy damage.
Strengths
Arbalests can deal plenty of ranged damage without worrying about being a soft target if the bad guys close in.
Can upgrade their already high damage by wielding heavy (20+ Weight) bows. One of the passives also ignore a bit of the enemy Armor.
Arbalests can strip heavy Physical Damage Reduction users "naked" with Buster Cannon, effectively reducing that to 0%.
Heavy Tackle can send someone across the map and inflict a free knockdown if you're using a Heavy Armor heavy enough, on top of it.
The stun caused by Blowback Cannon can single a target out of the fight for one turn and erase 7M, but the enemy will be more resistant to damage while stunned, so use it wisely!
Drawbacks
Reloading is slow, and speeding it up only adds to the rapid consumption of FP already involved.
Changes to stun made Blowback Cannon users have to think more before using their skill, as it now stun reduces all damage taken by 50% to compensate for the momentum loss.
Cannon attacks cannot be 'double tapped', as they cost 4M per use.
Spirit Mirror will be an early game nuisance, and Spiked Threads will ruin an immobile Arbalest's day, it will be impossible to remove someone from melee range if so.
Cobra users have a good chance to give you a bad time, as they can completely avoid your linear, frontal attacks, and use the chance to chase you down.
Arbalests are sometimes linear in positioning, as in, they need the enemy to stand in their 'line' of fire, and often have to stay immobile to do effective damage.
They're often, yeah, heavy and immobile due to high Battle Weight stacked, as it is needed for better use of cannon skills.
Unlocking
To unlock the Arbalest, one must equip Heavy Armor and win a battle using a bow as a Level 20+ Archer.
