I'm trying to accomplish the following
"The fighter temporarily raises his effective level by two. He temporarily gains the hit points, fighting ability and saving throws of a character two levels higher"
I tried stripping down the "enrage" innate ability from the Berserker, I get part way but thats not very clean
I then tried to use
#96 (0x96) Stat: Level Change 
Parameter #1: Statistic Modifier
Parameter #2: Type
Applies the modifier value specified by the 'Statistic Modifier' field in the style specified by the 'Type' field.
Known values for 'Type' are:
0 Cumulative Modifier -> Level = Level + 'Statistic Modifier' value
1 Flat Value Modifier -> Level = 'Statistic Modifier' value
2 Percentage Modifier -> Level = (Level * 'Statistic Modifier' value) / 100
Without success, any suggestions?
