Classy XP for Wizards, Thieves and Fighters

WTF the 5E light game doesn't really do XP, but maybe it should. So, here's a simple system. Based off this a bit. Hey, we're heading back to the Rainbowlands, so it's cool.

When you perform "deeds" and return to a safe haven and boast of them / prove them you gain XP as a die that you roll on the relevant XP table.

1. Discover ancient and forbidden lore - roll on the Seeker of Secrets XP table (Wizard table).
2. Retrieve treasure and loot from a 'dungeon' - roll on the Treasure Hunter XP table (Thief table).
3. Defeat / study a nemesis or new type of creature and bring back a trophy - roll on the Warrior table (Fighter table).
4. Invest proceeds in carousing / study / temple parties / foolish business ventures - i.e. the character's wealth gold is gone save for some change (Goldburner table).

Ideally, the difficulty / glory of the deed would determine the die. Basically, the deed has to be cool enough that telling the tale in a tavern would at least get the "heroes" a round of drinks and bed for the night. Something like this might work.

• Drinks are on the house - 1d4
• Hero of the hour - 1d6
• Memorable - 1d8
• They shall sing songs - 1d10

In practice, this is overcomplicated, so just a roll a 1d10, and the result also shows how impressed the townsfolk are.
