Fortifier

Triple your current Block.

Fortifier is an Uncommon potion that multiplies current Block by 3. Stacking Block first before use produces explosive defense. But this is a prerequisite — Block must already be in place, so the usage window is narrow.

For example, at 30 Block, using this produces 90 Block, enough to completely negate almost any attack. Timing it with a boss's big-hit turn is ideal. The key pattern is playing Dexterity buffs and Block cards first, then using this potion.

With low Block the effect is thin, and at 0 Block it does nothing. Dependency on deck construction and play order is why it sits at C tier. In Block-specialized decks, its rating jumps significantly.

• Use after playing many Block cards
• Harden defense in time for a boss's big attack turn
• Maximize Block with Dexterity buffs before using
