I am curious what house rules people play with when the game. This is mostly aimed at the 5E crowd but I am still curious what changes people think are so necessary there are House rules added for them.
In 5E we always played with Drinking a Potion was a bonus action if you had it 'on your belt'. Meaning everyone would have one potion they picked to be in a 'ready' state.
In 13th Age we allow a Potion to be drunk as a Quick Action if the player makes an Easy Save, on a fail they have to roll the save again on their next Quick Action.
In 5E we basically ignored Encumbrance and just made a judgement call is something was 'too much'. (13th Age already does this in the rules)
