# Pillager Outpost Overhaul v3.4 #
 - Fixed ALL of their files to new 26.3 file format
 - Fixed all "configured features" into features and are now in-line instead of inside a config object
 - Spawn now a captain with x3 health of a normal pillager
 - Cushioned up the place :)

   - it now generates either a damaged iron axe or a damaged crossbow each time, each with 20% chance to be enchanted
   - amount of emeralds can be 2 to 10 per roll,
   - arrows now vary from 5-10 instead of just 5,
   - lapis lazuli can now be 3-9 instead of 2 to 5,
   - dark oak saplings can now either be only 4 or only 8 per roll
   - the final roll for an exclusive item has chance for empty roll decreased
   - fixed inconsistency where Sentry Armor Trim was not in a set of 2, like in vanilla.
   - possible enchantments for #structure/illager_outpost roll now doesn't double up on quick charge

      - Chance: 1/7 ( illager hideout, woodland mansion, illager manor, ancient city, witch villa)
