I've been doing savestate practice against Bospider for like 3 hours and I can win maybe 60% of the time now without armor or subtanks.

I've figured out how to reliably deal with the small spiders but I'm still having trouble reading a path that hits more than 3 or 4 rungs.

I didn't see anything on the RTA Wiki about boss strategy or anything so I figured I'd pose it here.

My usual suggestion is to get bospider low health, so the fight is going at maximum speed, and just try to survive a long time. If you're able to read the patterns quickly enough to survive at top speed indeinitely, the rest of the fight should be greatly simplified.

Bosspider seems to be just being good at reacting, from what i can tell. basically getting used to read the patterns on the threads
