Crypts

Crypts are the primary source of equipment crafting materials in Total Battle. Running crypts consistently is how you gear up your hero and captains — skipping them means permanent long-term weakness.

Three Crypt Types

Type	Costs	Rewards	Research Required
Common	Tar	Crafting materials for standard gear	Crypts I
Rare	Rare Tar	Gems for socketing into equipment	Crypts II + Dragon Key
Epic	Epic Tar	Materials for unique-tier equipment	Crypts III

Common and Epic Crypts have a chance to yield double materials per hit. Rare Crypts do not.

How Crypts Work

A crypt has a total HP pool. Each march is one hit and deals a fixed amount of damage. The crypt clears when its HP reaches zero.

Key formula: Total Tar needed = (Crypt HP ÷ Damage per hit) × Cost per hit

Three stats affect your efficiency:

Stat	Effect
Exploration Cost Bonus	Reduces Tar consumed per hit — most reliable improvement
Exploration Efficiency	Increases progress per hit — only worth investing in when it pushes you below a whole-hit threshold
Double-Strike probability	Chance that one hit counts as two without extra Tar — pure bonus

Priority rule: Invest in Cost reduction first. Efficiency only matters when the bonus moves you past a whole-hit threshold; otherwise it wastes shards.

Carrying 10% more Tar than the base requirement triggers a bonus efficiency multiplier. Always carry slightly over.

Tar Sources

Tar Type	How to Obtain
Common Tar	Wellspring Ruins on the World Map; daily chests
Rare Tar	Dragon Keys from Elven Citadels on the World Map
Epic Tar	Tournament rewards; special event milestones

Base maximum march time is 20 minutes. The Ayrin hero, research, and talent points extend this — longer marches mean fewer trips to start manually.

Carter Captain

Carter is the dedicated crypt captain. Always assign him to crypt marches.

His bonuses reduce Tar cost and increase exploration efficiency
His bonuses are capped at a certain level — check in-game to confirm the current cap; do not waste shards past it
Investing in Carter early is one of the highest-return decisions in the game

Why Crypts Matter

Crypts drop the crafting materials for every equipment slot on your hero and captains. Better gear means:

Higher army strength and health in every fight
More Leadership (larger marches)
Better crypt runs (dedicated crypt gear reduces Tar cost further)

The gear loop accelerates over time. Start running crypts as early as possible.

Daily Habit

Run at least one Common Crypt per day. Even partial clears generate materials. The players who gear up fastest are the ones who run crypts daily without exception.
