I like it! It would at least put rogues back in their rightful place as the Best Stealthy Guy, as opposed to anyone with Pass Without Trace (seriously, what was the thought behind this spell?)

I still think they need a more "core" buff though. Like, they need to have a greater presence/impact in combat, and not just be skirmishing glass cannons (well, glass pistol).

I'd like to see them have

Opportunist
At 1st level, Rogues gain a pool of Opportunity Points, equal to their proficiency bonus. These points may be spent to use various class features. Opportunity Points are gained as an encounter begins (usually as initiative is being rolled, though the DM may rule that other situations also constitute an encounter). Unspent points are lost at the end of the encounter.

The rogue also gains an Opportunity Bonus; many uses of Opportunity Points allow the rogue to add their Opportunity Bonus to a roll. This bonus starts at 2, and increases as the rogue gains levels. It rises to 3 at level 6, 4 at level 11, and 5 at level 16.

If an Opportune Ability forces a saving throw, the DC is equal to 8 + proficiency bonus + Int modifier

Opportune Moment (1st level)
A rogue may spend an OP to add their OB to an attack roll, damage roll, or saving throw. This ability takes no additional action, though it must be declared before knowing the result of the roll.

Opportune Defense (3rd level)
A rogue may spend an OP to add their OB to their AC against a creature of their choice (i.e., the bonus only applies to attacks from that creature). This bonus lasts until the beginning of rogues' next turn.

Opportune Knowledge (6th level)
A rogue may add half of their rogue level to a skill check they are proficient in. This ability can be used after the roll is made, but it must be before the results are known. Once this ability is used for a particular skill, it may not be used again for that skill until the rogue completes a long rest.

Opportune Piety (8th level)
While rogues may or may not be religious, they are not above carrying around trinkets, holy books, and prayers "just in case," and even the non-believers among them can fake it well enough to get results when it matters. This ability may be used 2 + the rogue's wis modifier times, and it recovers after a long rest.

As an action, the rogue may spend an OP to rudimentarily channel divine energy. This may by used in one of the following ways
Heal: the rogue may heal themselves or another creature by touch. The target heals 1d6 x the rogue's Opportunity Bonus.

Turn Undead: Each undead that can see or hear you within 30 feet of you must make a Wisdom saving throw. If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage.

A turned creature must spend its turns trying to move as far away from you as it can, and it can't willingly move to a space within 30 feet of you. It also can't take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there's nowhere to move, the creature can use the Dodge action.

Opportune Arcanist (level 11)
As an action, the rogue may spend 3 OP's to cast a spell that they just saw being cast. In order to copy a spell in this way, several criteria must be met
- the rogue must have seen the spell being cast
- the caster must have been within 60 ft of the rogue
- the spell must take no longer than 1 action to cast
- it must have been cast since the rogue's last turn
- it can be of a level no higher than the rogue's Opportunity Bonus
- the rogue must have any necessary spell components on hand (experienced rogues will carry a focus or spell component pouch in case the opportunity arises)

Regardless of the time it normally takes to cast the spell being copied, it takes the rogue an action to cast it using this ability. If the spell has a duration, the rogue may maintain it via concentration, as normal. Int is the casting stat for this ability.

Opportune Brilliance (15th level)
(hmm something something copy something something?? I'm drawing a blank for the Opportune "capstone")
