Wild Magic sorcerers get the Bend Luck feature at 6th level (PHB, p. 103):
Starting at 6th level, you have the ability to twist fate using your wild magic. When another creature you can see makes an attack roll, an ability check, or a saving throw, you can use your reaction and spend 2 sorcery points to roll 1d4 and apply the number rolled as a bonus or penalty (your choice) to the creature’s roll. You can do so after the creature rolls but before any effects of the roll occur.
How would one resolve a situation where the two instances of Bend Luck are in conflict ?
[i.e. one person is trying to improve the roll while another is trying to reduce it?]
I know from DMG errata version 2.0 page 1:
Combining Game Effects (p. 252). This is a new subsection at the end of the “Combat” section:
Different game features can affect a target at the same time. But when two or more game features have the same name, only the effects of one of them—the most potent one—apply while the durations of the effects overlap. For example, if a target is ignited by a fire elemental’s Fire Form trait, the ongoing fire damage doesn’t increase if the burning target is subjected to that trait again. Game features include spells, class features, feats, racial traits, monster abilities, and magic items. See the related rule in the “Combining Magical Effects” section of chapter 10 in the Player’s Handbook.
The situation involves two instances of Bend Luck (a game feature with the same name), so only the most potent one should apply [since there is no duration here]. But in this case, how would that be determined?
Is the higher roll just taken regardless of whether it's helping the roll or hindering it? Or should I just assume they cancel out? Or maybe both effects just take place, and I add the effects together (since they are trying to do different things)?
