Non-visible Ability issues

I've got a unit that needs to have several non-visible abilities, in this case it is 2 passive abilities, one for evasion and one for hardened skin. In the map in question, I am using them as one ability.

The hero has those 2 abilities as unit abilities and a hero ability (that does nothing) tied to a trigger to increase the level of the hardened skin and evasion abilities (via an upgrade).

I set the hardened skin power to 0,0, no icon, no tooltips, nuthing, but it shows up as the green square of death. The Hero learn ability is setup the same way and has the same problem, but I can design around that if needed (currently the Evasion ability holds the tooltip info, you see).

If there anyway to get the green square gone? Any method, no matter how complicated will be used :)

I tried flagging the hidden abilities as item abilities, but still green square of death. I thought Item abilities didn't show up, perhaps only base item abilities?

Mucho thanks

Try setting it to 4,4
or you can delete the hardened skin abillity and just do a trigger that ads defense per level of evasion..

The 4,4 thing won't work, the fields cannot go over 2/3. I have the same problem myself, wanted to give a hero hardened skin and spell immunity visible as one skill when he uses metamorphosis. When i put one skil on top of the other it just got automatically moved to the next free spot.
Any other way to do this instead of making a trigger that simulates resistant skin by restoring hit points after each attack? Or maybe an invisible anti magic shield cast on the hero and triggers watching out for dispell? Any easier way?

The best you can do is to make the ability use some alphaed icon and use a space in the tooltips.
