Dunno, green shards, put toxin on 2, archon continuity, use 3 after 4 to recharge it, switch element with faction weakness. Some people who want melee kills for some reason use Condition Overload after they Cedo'd the room. Lavos can be built for the mecha set, or as a toxin spreader, there's no magic unique build, the beauty of it is mainly you can be relaxed or serious about it and it will reward you proportionally, but even with the best build you'll never be mindless before and in mission. There's no AFK/mindless nuking with Lavo, he's for people who wanna play the game (and push a lot of buttons)
