Seals in Blade Idle are items found in the relic tab that can be stacked to add extra stats to your character. You unlock them at stage 25-50. They come in all rarities and grades (Uncommon to Artisan, Grade 1-4).
Seal Stats
Seal grades 1 and 4 will contain various stats such as seal modifiers (Seal ATK%, Seal DEF%, Seal HP%), damage stats such as your typical crit, super and hyper crit dmg, or EXP and Gold bonuses.
Seal grades 2 and 3 will always grant you PEN and ACU, respectively, with increased rarity granting you more stats.
Upgrading Seals and Cost
When you collect a seal, it can be upgraded using enchant stones, consuming the seal and giving you a permanent stat boost. You must collect more of the same seal to upgrade it further.
Upgrading seals is very expensive. The initial costs of upgrading seals are as follows:
Uncommon Grade – 100,000 enchant stones
Common Grade – 150,000 enchant stones
Mid Grade – 200,000 enchant stones
High Grade – 300,000 enchant stones
Superior Grade – 400,000 enchant stones
Artisan Grade – 500,000 enchant stones
