GG Trigomas, didn't stand a chance against my FDBR. Normally when I fight this boss with this build it typically takes me like 40-50 turns to beat him, and I wanted to find a strategy that didn't take me that long to beat him, and that's when I remembered there's the Anchors Away Bow that has a weapon skill that deals a good amount of damage, figured it's worth a try and it did much better than I expected. This only took me 15 turns to beat him this way and the ramping didn't go too out of control it ended at 160.5% for the ranged damage modifier.
Also the reason I used the blood ruby misc was because it protects against energy, and I equipped it in case he ever decided to spend SP to use his energy attack. And I don't think the pet I used is better than baby egg here, but I wanted to use something different anyway.
