I need help with custom spells

ok i want to create a few custom spells
but i dont know how , cna you help me???
1 Run over- A mix of the Tauren Chieftains Shock Wave and the Wardens Blink spell
This spell is so , you target a area and the character moves into the place (best jsut simply teleport instantly) like with the blink spell or the Shock Wave this means even if you select a area not in the range you will get there (or in case of the tauren the hero wont move to get it into the range). And on the way beetween the target and the heroes position a Shock Wave will occur, thsi means all units beetween the hero and the target will get damage (possibly even stunned). is this possible?
2 Mighty guard - its the roar ability as a heor ability , it raises the armour of all units in the near , i simply dont know hwo to make it a hero ability
3 Absolute Defense- a passive ability , like the resistant skin of the Mountain giant so it reduces the damage dealt to the target by physical attacks by a certain amount of damage , i dont how how to make it a hero ability either.
4 SuperNova- it is sopsoe to be casted on a unit (or hero) the hero gets under the effect of star fall , so he cna move and all but the star fall gets attached to his body , when he will fight the meteors will damage him and all units in the near, So liek Starfall but you cast it on a enemy and this causes that he damages himself

well for now thats all cna you help me?

1) Lord Vexorian has made this spell among numerous other map makes... take a look at one of his older caster systems or something.

2) goto in abilities neutral hostile>heroes>battle roar then change the field that say denfense increase to what ever you want it to have and change the other fields to what ever.

3) goto hardened skin and check the field that says "hero ability" and set the levels to how many levels you want the ability to have. Also if you are basing it off of the night elf version, remove the research requirements. If you want a % damage reduction you have to base the ability off of spiked carapace

4) make a dummy ability based off of a targetable spell, then have a trigger that gives the target unit a modified version of phonex fire... the phonex fire ability has the star fall projectile art and caster art (havent tried it, testing it now)

but i suggest you try to stear clear of heavy triggering if you cannot do basic spell manipulationg (Q.2 and Q.3)

gee man thx
great help

sorry to bother you but ehhh
could you tell me how to make a spell that adds
Curse , Poison , silence , Fairie Fire , Slow etc
to a area spell
i want a mass weakening spell

You can trigger it, or...hang on...do you want to add all of those to one spell, or just one each?

Either way, I'm told that you can probably use an existing AoE spell eg Silence, and add buffs to it for the other stuff eg buffs for curse/poison/faerie fire/slow. Haven't tried it myself though, so don't know if it really does work.

Create a spell based off of Flame Strike. Turn it into a dummy. Create unit spells for your other buffs (poison, curse.. etc), and dummy units to cast these accordingly. Also, create upgrades to go with these extra abilities.

Events
Unit - A unit Finishes casting an ability
Conditions
(Ability being cast) Equal to Mass Weakness
Actions
Unit Group - Pick every unit in (Units in (Playable map area) matching (((Matching unit) has buff Weakness) Equal to True)) and do (Actions)
Loop - Actions
Unit - Create 1 Dummy Caster for (Triggering player) at (Position of (Picked unit)) facing Default building facing degrees
Set DummyCaster = (Last created unit)
Unit - Hide DummyCaster
Unit - Order DummyCaster to Human Paladin - Holy Light (Picked unit)
Unit - Add a 2.00 second Generic expiration timer to DummyCaster

Repeat the loop for each spell accordingly.

And for the abilities getting stronger if you want that:

Events
Unit - A unit Learns a skill
Conditions
(Learned Hero Skill) Equal to Mass Weakness
Actions
Player - Set the current research level of Dummy Curse to ((Current research level of Dummy Curse for (Owner of (Triggering unit))) + 1) for (Owner of (Triggering unit))

also i was playing around with lightning shield, and it can be modified to act like starfall. the only problem is that the waves fall every second and they effect ALL units... enemy, ally and even yourself

I changed my mind i dont want star fall
all is done
ok thx guys

awww... well i love that trick and i am going to use it.... its fun to play around with, casting the custom starfall on yourself, enemy, buildings all kinds of stuff.
