I've been making a mod for several new units, buildings, and Wonders. I have been trying to give two of the units inherent perks, rather than the normal inherent promotions The units themselves work fine, and I can create them without problem when I go to test it in game, but I can only make them if I use the version of the mod that doesn't attempt to give them inherent perks.
I have confirmed through testing that the problem is not with:
--The units (without inherent perks)
--The buildings
--The wonders

I have created a version of the mod that is only one of the units and its inherent perks, so that is where the problem lies. I have tried several ways of doing it, but haven't succeeded. This is what I want to give the units:

Perks:
<VisibilityChange>1</VisibilityChange>
<DamageToAdjacentUnitsOnAttack>15</DamageToAdjacentUnitsOnAttack><IgnoreRangedAttackLineOfSight>true</IgnoreRangedAttackLineOfSight>
<MoveAfterAttacking>true</MoveAfterAttacking>
<IgnoreZoneOfControl>true</IgnoreZoneOfControl>
<AlwaysHeal>true</AlwaysHeal>
<ExtraAttacks>1</ExtraAttacks>

So two questions:

1) Any ideas for how to give the units these perks at the beginning? I've tried a few things, but I'll try anything again, just because I may have missed a little thing that caused it to fail.

2) If I cannot give them perks, how do I create a promotion with those same effects, so that I can give the unit that promotion? I tried that a couple times, but it caused the promotion to show up for all units. I classified the promotion so that it should not be possible to choose it, but it didn't work.
