Overview
Thunder Loop (Lightning Ring evolution) is an A Tier evolved weapon that fires high-damage lightning strikes at 2 mana, scaling with Amount. With sufficient Amount investment, it becomes one of the top 2-mana finishers. Peak performance on Porta, whose passive continuously increases Amount.
Evolution Recipe
Lightning Ring + Duplicator → Thunder Loop
Duplicator provides Amount+1 before evolution, directly boosting Lightning Ring damage — strong combo even pre-evolution.
Recommended Gems
Priority:
- Triple Damage — multiplies on top of Amount scaling
- Amount-up — directly increases lightning count and damage scaling
- Wild — combo integration
- Attack-up — base damage boost
Amount-up gems compound favorably with the Amount scaling mechanic — every extra point increases both projectile count and damage multiplier.
Synergies
Crawlers
- Porta: passive Amount increases directly power Thunder Loop damage (top synergy)
- Ramba: dedicated Amount-increase crawler
- Giovanna: shared Amount increase mechanic
Arcanas
- Chain Link: combo staircase preservation
- Dancing Wind: Amount-linked additional hits
Relics
- Gem Hammer: gem attachment prerequisite
- Stardust Anvil: slot expansion + Might Power Up
Tips
Secure both Lightning Ring and Duplicator, stack Amount before evolving. Post-evolution, place in the 2-mana staircase slot with Amount gems to maximize output.
In Porta builds, Amount increases push Thunder Loop into top-tier finisher territory for single-target boss damage. Amount 20+ brings single-target burst into the top tier.
Tier Summary
General: A / Porta builds: S
Amount-dependent scaling — standard A without investment, S with Porta + Amount specialization.
