with this trick you can invoke a 9999 damage hit in two ways:
1/ leveling ayla up to lv 99 so her fist will transform into bronze fist than in a battle when she attacks and had the chance of performing a critical hit she will cause 9999 damage(this one's quite random)
2/this one won't only cause 9999 damage hit but it'll cause instant death even to lavos core, all you have to do is leveling frog techniques til you learn him frog squash, now if you notice its discription it says "lower HP=greater damage" first if you want to test it try it on spekkio's last form (wich looks like a pink Nu)with frog in your party than wait til he cast an aura like spell wich reduce party members Hp to 1 quickly use frog's frog squash and it will cause 9999 damage to him and instatly defeat him(to make a better results use it with lucca flare to cause frog flare duel technique) now go to lavos with lucca & frog with you defeat his innate form to start a battle with his core just let lucca and frog receive as much damage as their Hp is dangerously drop down cast frog flare and it'll destroy the three bits in one time so they won't be able to regenerate and voila you've beaten the mighty lavos.

1/use a strong physical tech(crono's spincut or confuse or double tech falcon hit with ayla )
-now they'll copy physical attk and start smashing you with iron ball(wich cause your HP to be cut to half )
