 # ACKS System for Foundry VTT (Unofficial)
 All the features you need to play ACKS in Foundry VTT. Forked off of Old School Essentials by U~Man and heavily modified.
 
+## Features
+Implemented ACKS encumbrance rules (uses coin weight instead of stone - 1000 coins to a stone)\
+Changed Ascending Armor Class to ACKS AC\
+Uncapped the dexterity and charisma bonuses\
+Changed default exploration checks (hear noise, open door, etc) to ACKS style rolls instead of 1d6 checks\
+Added more tweaks to the tweak section, to allow for ACKS proficiencies modifying throws, AC, and more.\
+Changed "Slow weapon" to subtract 1 from initiative instead of making the character last in the order.\
+Added a HOLD TURN icon to the Combat Tracker to remind the judge that a player has held their action.\
+Modified the encumbrance bar to reflect ACKS standard movement penalties while encumbered, and to show that on the bar\
+Changed default monster saves to match ACKS numbers (actually makes monsters a bit less resistant overall)\
+Added Auran languages and removed alignment tongues\
+### Optional
+Added exploding 20s in combat from HFH optional rules\
+Added BHR to the character sheet from HFH optional rules
+
