stats ignore everything except speed, speed replaces strength if you use slash, vitality if you use shadow blend, and you don't need instinct any ways. so pour stats into speed and ignore the rest.
skills integrity 4/4 slash 4/4 corrsion 1/4 (pre) envenom 1/4 (pre) infect 1/4 (pre) withdrawl 4/4 saveragry 4/4 predator form 1/1 evolve 3/3 endurance 1/4 o 2/4 (pre) crystilize 3/3 (pvp only) sharp senses 1/4 (pre) shadow blend 4/4 and for any remaining stats, do whatever you want, i suggest getting toxicant form for a 40% damage boost.
If u want more damage everything is same as above except u learn agile explosure? (i forgot the name) 3/3 and ur integrity becomes 1/4 since u dont have enough skill points. (predator form + toxicant form + shadow blend + agile explosure +withdrawal combo rocks!

pvp strategy if you opponentis a total weakling just shadow blend and slash, but if they can easily kill u since u will have 3k hp, then first crystilize em.after that, use shadowblend, then slash both their partners. then just leading strike for focus. after they recover from crystal, use it again! when theres 3 or 2 turns left in that crystal, us toxicant form, then shadow blend, when they are free, use withdrawl dealing around 10k-20k damage! you win. some faultys are if you face another speed bio, you will of course lose if you have less speed. and sonnys with huge hp might stand a chance, unlessthey have super low damage.
