Some abilities :) not too hard

[Rakavar]

hey guys, i was just wondering if anyone can help me with a few abilities that i need for my current project; Starless Nights (screenshots below)

heres are some of the spells that i need (I really would prefer GUI because i have no clue how to work JASS yet)

1. Backstab (DOTA: Stealth Assassin-Rikimaru)
2. Time Walk (DOTA: Faceless Void-Darkterror)
3. Permanent Invisibility (DOTA: Stealth Assassin-Rikimaru)
4. Meat hook (PUDGE WARS-NOT DOTA! http://pudgewars.informe.com)
5. Corrupted Arrows - A variation of flaming arrows (black instead of firey)
6. Water spells-I need ideas for my hero lol

anything else that'll be useful, and if someone can gimme a link to a tutorial or something like that about reading/exporting/importing JASS triggers id love to take a look at it. Any other spells that you think are great and would love to see in a map thats gonna be as great as the magnificent dota allstars, gimme a link

Thanks again guys. Heres some screenshots of my map. if your wondering why theres creeps/etc. its because its in BETA testing atm and im testing all bug/spells/triggers/units. i dunno if the pictures worked
