Tales of Xillia

Progress on this trophy carries over to a NG+.

You need to defeat 75 rare enemies for this trophy. There are two types of rare enemies: a stronger version of a regular enemy identified with a yellow warning sign above their heads, and a Bacura, which appears as a rotating brick. Bacuras will attempt to flee from you if they see you, but you can use a Dark Bottle to make them come to you instead.

It's unlikely that you'll meet 75 rare monsters normally as you play the game, so you'll have to farm them. It's recommended to do this during NG+, as rare monsters also provide more experience than regular encounters, which will help in attaining the level 99 trophies.

The best way to farm them is to warp to Sapstrath Deepwood SW, then move back and forth between Sapstrath Deepwood - SW Region and Sapstrath Highroad- SW Region, while checking only the monsters in the Deepwood area. There are always two monsters that spawn near the Deepwood entrance, so you can easily spot the warning icon as you enter. If you see a Bacura or a strong monster, engage them, then continue alternating between the two areas and battling rare monsters if you spot them until you get the trophy (credit to Ryukori for this image).
