Ruu's Alternative Pets
Pike
Pike is a pet that boosts Effect Resistance and Defense. Compared to Ruu, its Defense boost is lower, but it becomes easier to dodge debuffs, so choose between the two based on whether you want debuff resistance.
Paragon
Paragon is a pet that boosts Defense just like Ruu. It's a Rare pet obtainable through Pet Crafting and relatively easy to raise, making it a solid option to raise as a stopgap until you secure Ruu.
