Types Basic, Concentration, Death
Selection Choose any action your character can normally take that costs MP.
Activate You spend twice the time and twice the MP performing the selected action.
You get the normal effect of the action you're using but treat its tier as 1d4 tiers higher than normal (and your effective level as twice this much higher). However, you take 1d12 conditional mental damage per additional tier added and you take 1d4 ongoing bleed for 1 minute thereafter. As this damage is self-inflicted, it's armor-negating and resistance-negating.
Going 2 hours without spending MP and taking a short rest ends the condition preventing this damage from being healed.
If you use this action while already suffering from its conditional damage, the conditions needed to remove it worsen to "going 24 hours without spending MP and taking a long rest".
Each time you use this action while suffering already from its effects the 1d4 tier increase and bleed gets a cumulative +1 but there's a 10% cumulative chance it will automatically deal an amount of damage equal to your current hit points in addition to the damage listed above. So the first time you use it 1d4/0%, second time 1d4+1/10%, third time 1d4+2/20%, fourth time 1d4+3/30%, etc.
