Add Vampiric Modifier

[TheMarstonConnell]

Summary

Adds a new Vampiric modifier that provides a high-risk, high-reward lifesteal mechanic for skilled players.

Features

• Lifesteal: Heals player for 5% of damage dealt to enemies
• Penalties:
  • Prevents natural health regeneration (Hunger I effect)
  • Drains 0.5 hearts every 30 seconds when not in combat
  • Must actively fight to sustain health
• Visual feedback:
  • Red damage particles when healing from hits
  • Soul particles when taking drain damage
• Tooltip shows combat state ("Fed" with timer / "Hungry!")
• Not compatible with Necrotic modifier to prevent overpowered lifesteal stacking

Implementation Details

• ID: vampiric
• Crafting Item: minecraft:fermented_spider_eye
• Type: Hurter + Holder modifier
• Implements EntityHurtModifier and HoldModifier interfaces
• Uses magic damage source for health drain (bypasses armor)
• Tracks last hit time for drain mechanic

Balancing

• 5% lifesteal is lower than Necrotic (10%) to balance the continuous drain penalty
• 30-second timer encourages aggressive combat
• Health drain creates meaningful risk - players can't just use it situationally
• Forces a commitment to aggressive playstyle
• Designed for skilled players who can maintain combat momentum
• Incompatible with Necrotic prevents stacking multiple lifesteal effects

Gameplay

This modifier rewards players who stay in combat and punishes passive play. Perfect for challenging boss fights or mob farming, but requires skill to manage the health drain effectively.
