Blaz da Tamin' Masta
From RoR Wiki
Another mandatory boss (dual minibosses) before Arathremia. This encounter is a public quest as well, so gold bags include the gloves and boots of the Redeye Set.
Tactic
This Goblin hero will come with his Giant Spider friend Velkyrix. Only Blaz da Tamin' Masta must be killed to achieve the quest, but you will probably have to kill the spider as well since she will not despawn, thus blocking the way.
Focus on killing Blaz da Tamin' Masta first, then go for the spider.
/!\ Caution: The giant spider will lay eggs all around her during the fight, which will spawn multiple adds if hit. Avoid AoE at all costs !!!
Stay in max range to avoid AoE from both bosses, and tank them apart if possible (those can be both solo-tanked with strong maintank)
