New apperance for heroes

I want to make the heroes change apperance every 3. level - but they have to keep items, xp etc.

How can i transfer this to the new hero, who's gonna replace the old one?

I would imagine you store the items in an array, and then have it set when the new hero comes, give the integer to the heroes inv.

then i need to ask a n00bish question, i guess: how do i set arrays and intergers?

Ok, look at this:

Event:
Unit - A unit owned by Player 1 (red) Gains a level
player 2
player 3
.... etc.

Conditions:
(Hero level of (triggering unit)) Equal to 10
(Unit-type of (Triggering unit)) Equal to [name of hero who gains level up]

Actions:
Unit - Replace (Triggering unit) with a [New unit] using The old unit's relative life and mana
Hero - Set (Last replaced unit) Hero-level to 10, Hide level-up graphics
Hero - Give (Item carried by (Triggering unit) in slot 1) to (Last created unit)
Hero - Give (Item carried by (Triggering unit) in slot 2) to (Last created unit)
.... and so on until "slot 6".


This works =D =)

Um When you replace I'm pretty positive it gives you the items you use to have on that hero.
