Just a tip for everyone struggling with bosses. First clear all mobs in all the levels of all dungeons this will provide a ton of xp loot and souls. before doing legendary mobs stack up on pots smallest for world 1 medium for world 2 and 3 and largest for 4+ about 20 should be enough for world 1 50+ world 3+ keep the mob ranged at almost all times. For Archers this means bow slam and frost arrow are key. If they have a special... bow slam it unless its the blue lizards then just back up a little. This has kept me alive for all legendary creatures so far. Will update if island 5 is any different.
