Castlevania shows us the way, as usual:Nath wrote:A mist form ought to make you immune to some type of attacks (grappling, stake, crossbow bolt...) and allow you to sneak under doors. You can possibly balance bat and mist forms by making the former fly faster, but overall Mist Form seems better outside of long-range travel situation.
Bat form is for getting places you can't normally get to (usually vertically). Your upgraded bat form also lets you move really quickly through the air in short bursts. I don't know if you want to keep the Wing Smash attack specifically, but hey maybe that's a splatbook filler power.
Why you would want a Bat Form over regular flight is that it's way more discreet in urban settings. Unless you can fly and turn invisible, which should probably cost extra mojo as compared to just turning into a bat.
Mist form is for getting through tight spaces you couldn't normally squeeze through; grates, keyholes, closed windows that aren't well-sealed. Mist just kind of drifts slowly around, though, so you don't really want to use it for transport. On the plus side, you also can't meaningfully harm mist without something like a portable compressor. The Ghostbusters could probably deal with a vampire in mist form.
As for the Wolf Form... I guess they can run faster and longer than a human, but that only really matters if you don't have access to a car. Also I guess wolves can swim, whereas Alcuard cannot. Plus wolves have an unintentionally cute MIDI bark.
Lest we forget, Gary Oldcula also transforms into a swarm of rats.Nath wrote:Turning into a flight of bats (or any other swarms) may count as a defensive ability, but having to deal with attacks that may or not affect all or a majority of bats may not be worth the hassle game-wise. So on one hand, "there is that 1958 movie where Dracula turns into a flight of bats" and on the other hand, "you play one character so you turn into one bat" seems reasonable rule-lawyering.
