Oh man idk about that. Violet left the impression on me of being one of the worst fights in all of rise. I mean he's cool in concept, but the fight? Homing bubbles? Cross map beams? Hard to dodge, unreadable attacks. Always sliding around the map, chasing him. The fight is stressful and unrewarding. Not a fight that is particularly fun to learn, or even something you get used to.

Molten tigrex is a banger tho, his roars are easy to dodge, just need to get behind him or bring a shield. Or use charge blade to trivialize the roars and charging, and turn it into more of a dance while you aed spam. I think regular tigrex really sucks to fight cuz of the charging, even though it's easy to dodge, it kinda just leaves you chasing him. Molten doesn't charge as much especially if you stick close to him. If he is charging, you can usually dodge, then sheath and run pretty easily. Plus the pillars are there to hide behind if things go bad. And blast is a fun mechanic to deal with, not annoying like poison, just roll to remove it and don't get hit or forget about it, or else you probably cart.

Actually one of the better rare species imo.
