The best you can use
Sign in and set up your character to see the best gear you can use.
Estimate with the game's fight rules: 2d10 plus accuracy against a defense of 6 plus armor modifiers; a critical hit (two tens or 10 over the defense) deals ×1.5; damage minus the armor for that damage type, at least 1 per hit; base health 60; a turn every 10 s. Natural defense, skill bonuses, range and terrain are left out.
