Must have Str: 14+  OR  Con: 15+

• You get a Str: +1 or Cha: +2  [max of 21]
• When half your hit points [max, rounding up] is depleted you may deal an extra dice roll to your damage
• When you roll a critical hit, every creature in a 15 foot sphere [Including your teammates!!] is frightened [condition] until their next turn unless they are immune to the condition

[For example, if you have a 100 hit point max, and you have 50 hit points left, an attack with a club deals 2d4 instead of 1d4]
