I should clarify, Physical Biological CAN be built around speed and strength, but piercing damage mixed with Shadow Blend (Which increases speed by 300%) deals A LOT more damage than strength build
Quite honestly, there is only 1 good build for Bios - the Speed build.
You need: Shadow Blend
And at least 1 of these three abilities that scale with speed: Slash (160% str. + 160% sp., and decreases healing) Withdrawal (the best, but with long cooldown) Vicious Strike (The least effective, but it's got healing)
And this focus regenerator: Integrity - 25 focus and 3% health per turn.
And these optional abilities Crystallize - stuns opponent, shielding them from damage for 2 / 3 / 4 turns. Reform - heals teammate or yourself for 65% (!) of your max health Agile Exposure - increases damage taken by 100% (for your opponent) - hits most of the time if you have shadow blend. Toxicant Form - Increases damage by 40% for 4 turns.
