Vampires shifted into some other form should appear on warning as their true difficulty, rather than the difficulty of their current form. Attentive players are then rewarded for noticing that a wolf or fog cloud is an unusual difficulty 4.

Fix vampires shifting into fog clouds as an escape method because this doesn’t currently work with fog clouds being slow and easily killed.

• Normal fog clouds can still be slow, but vampshifted fog clouds should have their regular form’s speed.
• Fog clouds in general should be very hard to land a hit on, with “your attack passes harmlessly through” like a ghost nearly all the time (allowing critical hits only?), or all of the time, if you are not engulfed. Fog clouds that are fleeing, like vampires running away, will not engulf the player.
• If a vampshifted fog cloud is pinned down and has nowhere to go, it can pass through the squares of a number of monsters blocking its way and land somewhere else, provided that space is within a few spaces. This prevents the player from trapping it in a corner and beating it to death.
• At some point, the vampire must turn itself back to normal, and not stay in fog cloud form forever.

Vampire bats that are actually transformed vampires treat their bite attack as if it drains life (as with a regular vampire’s bite) rather than dealing physical damage.

Not all vampires are capable of shapechanging. Some of them will remain in their ordinary form. A smaller fraction of vampire lords is the same.

When a vampire is killed in shapeshifted form and reincarnates in its normal form, it comes back at half health. Due to this, vampire AI sometimes chooses to stay in normal form at full health.

The ring of protection from shape changers should apply to the wearer as well as other monsters; if the wearer has lycanthropy, they will not transform; if the wearer is a different shapechanger like a vampire, they cannot transform.
