So, on the Curse. If we are talking about in game benefits, Agelessness (Or Endless) is the very definition of a role-playing quirk.  It has zero mechanical advantage unless you tack on (Cannot be magically aged).  Otherwise, it's relatively useless as we very likely will never cover enough time to make it matter and even then, it would still only have role-playing uses. With that in mind, I don't necessarily want to give Eloric a mechanical flaw while gaining absolutely no mechanical advantage. (Which I guess I kind of did by sacrificing a magic item slot, but...I don't really want to add on to that.) So as you said you're not a fan of Role-playing drawbacks anyway, I'll just keep it simple and leave it be. 

Being immortal does have benefits.  The whole not dying from aging or being magically aged is one of them.  You being immune to a ghost's main attack may not give you a huge boon in another game setting because you may never meet one.  But in Ravenloft, you will most definitely be encountering a ghost.  Probably multiple ghosts.  So it should be worth more than a sad post now and then.

As far as Cantrips.  Honestly, my spell was my answer to the cantrips question.  The duration allows it to mimic the @Will use of a cantrip, albeit quite a bit weaker at lower levels.  This keeps the flavor of 2e nicely, while adding a touch more utility to my wizard.  So if you're allowing my spell, then we don't need to worry about cantrips unless you want to figure them out for your priest. As far as spending hours setting things on fire, the spell is direct damage with no DoT or AoE damage components, so it shouldn't be a worry as it just doesn't work like that. On the spells elemental types, I can totally change Force to Earth. I think it makes more sense anyway now that you mention it.

It completely slipped my mind that 2e had a literal cantrip spell and didn't clue in when you said it takes a 1st level slot.  

In that case, we could just give all wizards either a free cantrip spell at half duration.  So 1/2 an hour per level to mimic the lower power of a 0 level spell compared to a 1st level.  If they want more cantrips then take the spell.  

Or

They can have a free cantrip spell that last 1 minute per level but they can split it up into 1 minute increments.  I kind of like this one because you rarely use cantrips for very long and it lets you split the duration for when you need them.

As far as your, Eloric's Energy Bolt, I keep thinking that 1 hour per level is too long but then I try to remember that really that's not much different than someone just buying and using a bow except they can use it for 24 hours a day and you can us it for 1/hr per level.  It's also more thematic for a wizard to be firing energy bolts.  So you can keep your spell buy I reserve the right to change my mind if for some reason it's causing problems.
