Please remove Ritual Dagger

Bring back Scroll of Healing to Undead Shop. It was much more relevant for Undead going ghouls. They already have blight for out-of-combat regen, and ritual is strictly worse than scroll of regeneration, redundant, and requires sacrificing a skeleton, which usually means buying a second item. Make scroll of healing available at tier 2, that would’ve been a better solution than ever inventing this item. If you really feel Undead needs more out of combat regen, just improve blight regen or make sacrificial skull cheaper.

You are right about removing Ritual dagger. I posted it a while ago:

Do NOT add scroll of healing to tomb of relics. It exists in goblin merchant which makes the area near goblin mechant more contested instead of “turtle tactics” at your base. It’s a bad idea to improve blight regen since it’s already strong and doesn’t allow different tactics for instance it doesn’t heal Beastmaster or Tinker if you play them as undead. Sacrificial skull was already improved years ago, for instance graveyard requirement was removed.
Instead focus on the undead unit abilities that heal:

Statues are mandatory because healing abilities of other undead units and items dropping from creeps are currently lackluster which doesn’t allow for different tactics, so you want to nerf the statue like this in the end:
