Common Tar is used to explore common Crypts. Your Tar Workshop produces this resource constantly until it's at capacity. Your maximum capacity of Tar is also determined by your Tar Workshop. The cap can be increased by researching technologies and leveling up your Hero's talents. You can also get common Tar from packages and Clan chests, purchase it using Gold, or obtain it as a reward for reaching new battle pass levels in the Triumphal Challenge.

Rare Tar is used to explore rare Crypts. Rare Tar is harder to come by than common Tar, as this resource cannot be produced in your City. You can get more rare Tar by purchasing it using Gold or finding it in packages. You can also win rare Tar by placing in the top 100 in most regular events and global tournaments or obtain it as a reward for reaching new battle pass levels in the Triumphal Challenge.

Epic Tar is used to explore epic Crypts. Much like rare Tar, this scarce resource can be purchased using Gold or found in packages. You can also win it by placing in the top 100 in most regular events and global tournaments or obtain it as a reward for reaching new battle pass levels in the Triumphal Challenge.
