I've worked from scratch step by step on a new status effect (instead of copying one) and a spell, started with a shout and now trying with a target as shout had no effect. Sadly the target version has no effect either. I can target myself or an ally as it should be (even though later on I will deactivate self targeting but for test purpose I don't mind).

Now the problem is that my spell doesn't proc any effect, in order to get some valuable help I will simply give you all the columns I filled and with what for both my Target_Spell and my StatusEffect. Anything I don't put means I let a blank space (so if you see anything important missing that may be my problem).
Here it goes!

For the Target_Spell:
Name: HelperShout
SkillType: Target
ForGameMaster: Yes
IsEnemySkill: No
Ability: None
Tier: None
ActionPoints: 0
Cooldown: 0
SkillProperties: HELPER,100,1
TargetRadius: 15
CanTargetCharacters: Yes
CanTargetItems: No
CanTargetTerrain: No
MemoryCost: 0
MagicCost: 0
TargetConditions: Character;Ally
UseCharacterStats: No
UseWeaponDamage: No
UseWeaponProperties: No
Icon: Skill_Summoning_DominateMind
From DisplayName until CastEffect (+TargetEffect) are all copied from DominateMind (I spare you the details it's not super relevant considering my bug anyway)

As for the Status, I went for a Status_DAMAGE as I thought it would be the most neutral possible since Charmed change side of AI in addition to loss of control, here it goes:

Name: HELPER
Type: EFFECT
InitiateCombat: No
BringIntoCombat: No
DisplayName: Helper
Description: Your companion is being controlled by the AI.
Icon: Skill_Summoning_DominateMind
LoseControl: Yes

So to summarize everything works from the creation of the skillbook to learning it etc it starts not working as intended when I basically use the spell. I can target myself, my ally but it has no effect whatsoever and the description of the spell is wrong as well (no status effect is displayed for instance).

What have I done wrong ?

I used to make it work at least with bleeding and here I can't make even work a bleeding, I clearly miss a detail but which ?
