The good strategy is the same strategy for most monsters: Hit him and don't get hit.
Learn his attacks, only 2-3 of them actually poison you and they have ridiculous tells:
- The deadliest attack is the one where he spreads his "wings" (is that what these things are? who knows) and slams the ground, spreading poison everywhere. The tell for this is really obvious, if he stands still for a bit and then reels back a bit, get out.
- One of his eggs is a poison bomb. If you actually get hit by this,
- He can spit poison as well. When it looks like he's going to do it, dodge to the side. All of his attacks are dodgeable by rolling left or right, so it's always safe to do so.
