15k is probably a decent benchmark, it depends a lot on your monster's abilities and your matching skills though. If you have a shield/absorb/invincible and match hearts at the right time you you can get by with even less, especially because this boss doesn't have Surge or anything, just Stun, which actually gives you a perfect chance to heal.
