Hey there!~ :3 I was just wondering if ya still take suggestions, but just in case, here's one i thought would be interesting:
Wood Elf/ Forest Elf
*Stat increase when boss is defeated: +1-3 Ranged damage , 2-4% Movement Speed Increase, +.5 arrow velocity (Also if it sounds interesting to you, maybe replace one of those with something like Increase inflicted status effect duration and/or chance of infliction (ie Flame arrow's burn or Poison duration on enemies))
*Special: Empowerment in Forest Biome (Like you had done with Blood Knight or Tainted Elf but maybe with with a little bit less of a boost (Instead of 3x, maybe 2x) since the biome is common and easy to live in).
*Ability:
Duration 10 - 15 seconds : When using a bow, the player can hold the mouse button to rapid-fire arrows. Arrows can pierce through enemies and deal 10% more damage. Adds the ability to
entangle and
poison enemies in thorny vines
(entanglement should not have an effect on bosses) (Entangled enemies cannot move and are stopped in their tracks completely for 2-3 seconds) (adds them alongside the abilities the arrow originally has like fire arrow's ability to burn enemies).
If ya think anything needs to be added/taken off of there, feel free to do so,
and if any ideas sound interesting to ya for another class feel free to use them as you wish
Hope ya like the idea ^^
