[The "spirit" offers no more words. Tattoi's running low on spare steam, so he can do just one more thing before he needs to refuel. The hissing starts up again, but continuous this time - if Ian could see Tattoi, he'd notice that his arm had changed form and steam was running through it.]

[Since he can't, though, all he might be able to notice is a crackle of electricity building up within the steam-spirit... and once it builds up enough, it's released in the form of a bolt of lightning. Aimed right at Ian, or the tree he's hiding behind; preferably the former. |Db]
