I'm trying to make a character that can help folks with the last handful of bosses and also enjoy some duels and invasions. I'm currently at 139 but the reason I want to go up is that it's hard to make super optimized builds for split stats. Do y'all still get summoned for those last few bosses at higher levels? I was looking at 150-200 range but I'm not sure how many people are fighting endgame/DLC bosses in that range and I don't want to commit to a level that forces me out of the range of summons.

Any advice?
