- Weapon socket: Chance on hit to grant lifesteal (Chipped: 7% lifesteal).
- Armor socket: Amplifies all healing received (Chipped: +10%).
- Backpack slot: Once per battle, after a 5-second delay, deals magic damage to the enemy with 150% lifesteal attached (Chipped: 4 damage).

Rating & Analysis
Ruby is the most generically useful of the five gems — the classic "just grab Ruby if you're unsure" pick. It adapts to both offensive and defensive boards and never goes dead in any class. Weapon Ruby grants permanent effective HP through lifesteal, while armor Ruby doubles down on the scaling of any healing-focused build.
Perfect Ruby (35% lifesteal) represents roughly a 5x leap in per-hit healing compared to the lower tiers, which makes the Flawless-to-Perfect promotion a genuine game-changer.
