What is pity in Catch a Monster enhance?

Pity is a counter that increments each time an enhance attempt fails. When the counter reaches the pity cap for that enhance level, the next attempt is guaranteed to succeed (100% chance). The cap increases at higher levels — for example, the cap at +3 is 4 failures, at +5 it is 7, and at +7 it is 15.

What is the success rate at each enhance level in Catch a Monster?

Confirmed rates from in-game screenshots: +0 is 100%, +3 is 40%, +5 is 20%, +7 is 10%. Rates at other levels (+1, +2, +4, +6, +8, +9, +10) are community estimates based on geometric interpolation. The calculator clearly marks which values are confirmed versus estimated.

How many enhance stones does it take to go from +0 to +10?

On average it takes roughly 75–100 enhance attempts to go from +0 to +10, but the p90 (unlucky 10% of players) can require 150 or more attempts. Use the simulator on this page for exact percentile estimates based on the current pity table.

How many copies do I need to fuse a pet to SS rank in Catch a Monster?

Fusing a pet requires multiple copies of the same pet plus a catalyst item. Exact copy counts and catalyst requirements vary by rank step and are still being verified by the community. The Fuse tab shows the confirmed stat increase (×1.30 per rank) while copy/catalyst costs are marked as unconfirmed.

Does enhancing a pet affect its HP as well as DMG?

This is currently unconfirmed. The calculator assumes enhance affects both DMG and HP by the same multiplier (+10% per level) until community data verifies the exact formula. Both values are clearly flagged as estimates.
