how to exceed values?

[InfernalTater]

i recently opened an unprotected version of a map, as the person said i could mess around with it. he has not been on in a while so i cant ask him so ill ask you guys:
how do you make a value exceed the maximum?
examples of what i saw in the editor: health regeneration at 3500 (maximum is 1000). when changing the levels of an ability with auto-raising mana costs the numbers may exceed the maximum value with anything having multiple levels to change from 1 to 10 and then back, yes, but how to change values without doing that, as health cannot be treated that way.
also, i saw in the tilset, there were 26 used tiles, i actually had to scroll through them... and the remaining was -13. how do you do that?

You can not, the WC3 engine only supports 16 tile pallets. Some use 2 slots and this applies for triggers as well.
