This custom rule set is meant to take the DM arbitration out of the WILD MAGIC sorcerous origin. While this revised approach offers a more random set of outcomes, it places the risk/reward choices firmly in the player’s hands, even if those choices are at times blind.
The WILD MAGIC SURGE and TIDES OF CHAOS rules on page 103 of the PHB are replaced with the following rules.
Starting when you choose this origin at 1st level, your spellcasting can unleash surges of untamed magic. Immediately after you cast a sorcerer spell of 1st level or higher, the DM will secretly roll a d20 and reference the result of the roll on the Wild Magic Surge table to determine the outcome.
TIDES OF CHAOS
Starting at 1st level, you can manipulate the forces of chance and chaos to gain advantage on one attack roll, ability check, or saving throw. When you do so, the DM will secretly set aside a Tide of Chaos (ToC) token denoting you have used the ability. Whenever a Wild Arcanum roll is made, the DM will add a number to the roll equal to the count of ToC tokens set aside.
If you finish a long rest, all ToC tokens are discarded without effect.
WILD MAGIC RESULT TABLE
You have unleashed a surge of uncontrolled arcane power
The DM will instruct you to roll on the Wild Magic Surge table to create a random magical effect. In addition, if you have any ToC tokens, your DM will secretly discard one.
The arcane chaos surrounding you has caused a ripple in the fabric of reality
The DM will instruct you to roll on the Wild Magic Surge table to create a random magical effect. (The DM does not discard a ToC token.)
*Together these two rules mean that once you have 4 tokens, you’ll never be sure how many tokens you have until you either cause a storm or finish a long rest
Your meddling in the nature of magic has resulted in a reality shattering event
- Immediately suffer 1 damage of a random type per ToC token set aside
- roll 1d6 and reference the result on the Wild Storm Table to determine the outcome of the powerful surge of raw arcanum
- your DM will discard all ToC tokens
