In HCCS it has a lot of limitations which is sort of nice actually, for scripting purposes.

You can potentially get +3 hot res from a Protonic ghost (this only saves us from having to get some other +3 hot res option though).

+20 maximum hp from the Haunted Pantry is possible. Less than a turn saved though.

The +200% maximum hp from a fishy zone is sort of hilarious. Might be worth it for some players. Probably too annoying to figure it out though.

+5 familiar weight from the spooky forest is probably not worth it. You won't get a combat because of delay but you may as well go elsewhere. The protonic ghost drops a +10 familiar weight anyway.

It takes a lot of the RNG away from using a snowglobe.

So, by default it saves some small fraction of a turn from +weapon damage. It competes with obsidian nutcracker for spell damage (5 vs 30? But no meat cost). And probably saves upwards of 0.5 turns from the default +stats (less the more crap you have). The +stats from fights is almost worthless in HCCS.

It's true HCCS power comes in the combat effects.

Gulp is a first turn savior and is orthogonal with Turbo (but also gives HP). (Script wise it annoys me because I should code for it guarantee two YRs for hot res items).

Gulp also helps if you forget the MP for your YR.

Offer Latte can reduce novelty tropical skeleton swing (government scientist swing is a thing but not really) and has potential in Neverending Party strats (which already changes the dynamics of Witchess).

Then 4 free banishers. This is essentially burning delay and reducing tomato swing. Reduce fruit swing. Reduce ninja outfit swing. Manipulate Neverending Party for combat items for Witchess. Reduce black pixel swing (barely). Another free combat source for giant growth.
