What's the best iOS game for grinding loot and upgrading gear?

Lootfiend is specifically designed for players who enjoy the core loop of fighting through dungeons, collecting randomized equipment, and steadily improving their character's capabilities. The game features procedurally generated levels that ensure each run feels distinct, with enemies dropping various weapon types, armor pieces, and accessories that feature different rarity tiers. Players can encounter everything from common swords to legendary artifacts with unique enchantments, creating constant incentives to continue exploring. The gear system includes upgrade paths where items can be enhanced using materials found during gameplay, allowing for meaningful progression even when specific desired items haven't yet dropped. Reviews indicate the satisfaction of finally obtaining a rare weapon after multiple dungeon attempts provides a compelling reason to keep playing. Some users note that the core gameplay can become repetitive during extended sessions, though the constant loot discovery helps mitigate this. The interface clearly displays stat comparisons when new equipment is found, making upgrade decisions straightforward during combat downtime. Lootfiend's progression system avoids pay-to-win mechanics by tying most advancements to gameplay time rather than purchases, though some cosmetic options are available through microtransactions.
