Sword x Staff: Heavenly Condemnation Thunder Rainbow Tier Upgrade Guide

Upgrading the Light-type active skill Heavenly Condemnation Thunder to the Rainbow (Color) tier in Sword x Staff significantly improves damage scaling, skill activation frequency, and area-of-effect efficiency during automated combat. To reach this milestone efficiently, stockpile your upgrade materials during seasonal downtime rather than spending resources incrementally on lower-tier banners.

Performance Gains from Rainbow Tier Upgrade

Evolving your primary Light skill to Rainbow tier provides direct combat upgrades that improve both single-target DPS and crowd-clearing performance:

Higher Damage Scaling: Base multiplier increases ensure automated rotations deal substantially more burst damage against high-health targets and boss encounters.
Expanded Splash Coverage: Area-of-effect hit range expands, allowing auto-combat target selection to clear groups of enemies faster without wasting heavy hits on dying targets.
Increased Activation Frequency: Shorter effective downtime between casts maintains steady DPS during prolonged fights in dungeon and campaign stages.

Seasonal Downtime Resource Allocation

Resource accumulation during off-peak seasonal windows prevents bottlenecks when evolving skills to the final tier. Focus your daily farming routines on three core components:

Resource Type	Recommended Source	Usage Priority
Skill Vouchers	Off-season event tasks and savings	Save specifically for banners featuring Light-type skill components.
Upgrade Crystals	Daily mission rewards	Stockpile to fulfill raw level prerequisites upon reaching evolution thresholds.
Elemental Shards	Dungeon rotation farming	Target Light-type shard nodes to prevent bottlenecks at the final evolution tier.

Balancing Skill Evolution with Gear Stats

Active skill damage scales off your character's baseline attributes. Evolving Heavenly Condemnation Thunder without upgrading base stats leads to diminishing returns.

Maintain a 2:1 Resource Ratio: Allocate two parts of your accumulated currency to skill evolution materials and one part to refining gear affixes.
Prioritize Multiplier Stats: Focus gear upgrades on Base Attack and Critical Hit Rate, as both directly multiply the skill's Rainbow-tier damage output.
Adjust for Elemental Resistance: Maintain a secondary skill set of a non-Light element. Relying entirely on Light damage creates progression roadblocks against enemies with explicit Light element resistance.
Pivot Post-Milestone: Once Heavenly Condemnation Thunder reaches the Rainbow tier, shift seasonal material investment toward secondary support skills to build a balanced skill loadout.
