Making spells (buffs) last longer without using persist

[DavidWL]

Extend/Echo/Circle Magic for longer longer buffing ...

- Image in a spell with duration 10 min / level.
- Cast by a level 20 caster with circle magic => CL 40.  With some optimizing, we can easily get to CL 42.   
- Extended

14 hours per casting.  +1 level adjustment

- Image in a spell with duration 1 min / level.
- Cast by a level 20 caster with circle magic => CL 40.  With some optimizing, we can probably get to CL 44.   
- Extended
- Now make it an echoing spell
-> 88 minutes per casting - 8 per additional casting

6 continuous hours per spell slot (8 hours total).  +4 level adjustment (+1 and +3).

For spells with hours per level duration, it can last almost 4 days with one casting.  For spells with a duration of 1 day, they can last 2 days with extend, so you can cast it the day before, sleep, prepare your spells, and then go out adventuring.

But what can we do to make min/level and 10 min / level spells last a close to a day as possible?  (Or longer!)?  Without using persist ...

Best,
David

The best you can do is apply Echo Spell and boost the piss out of your CL until the spell lasts longer than an hour (easy for 10/CL, piss-hard for minute duration spells).You then cast it every hour.

Or just deal with the whole problems of being vulnerable for a few minutes between encounters.

Elder Giant Magic from SoX (isn't it where Echo Spell is from?) allows you to boost your CL by up to 3 if you spend extra rounds casting the spell (+1 CL per extra round spent, up to +3). I think it's pretty neat for even low-level casters who want their daily buff to last a few more hours.

[BowenSilverclaw]

That's pretty nice

That's useful, but don't you have to be a Giant for it?

Still, this means we can get a base CL of 45 for the majority of your spells.

Primordial Half-Giant with LA-buyback?

Primordial Half-Giant with LA-buyback?

Or just plain old half-giant.

[BowenSilverclaw]

Yeah, but if you're going with a Half-Giant caster you might as well tack on Primordial as well. Not like it costs you anything extra

[Salt_Crow]

Nope, it's Spellcraft 9 ranks OR Giant. Giants gain +4 bonus to concentration check and can use EGM feat to improve their spell-like abilities (if any)

[Tshern]

So rewrite the headlines and dump the half-giant.

[DavidWL]

Actually, it occurs to me that with a repeat echoing spell, you can double the effect of echoing spell, as well as staggering the instances where it lasts less than 60 minutes ->
=> 1 min/lvl -> 14 hours

This costs +3 repeat +3 echoing +1 extend for +7, but in a game where persistent is banned ...

Alternatively, if you have a metamagic specialist build, then you could pull the above off with no LA (I've been playing with that idea).

Shadowcraft Mage with gnome illusionist 5th sub level and extend spell gets +300% duration on all Illusion (and effectively evocation and conjuration creation/summoning) spells.

So at caster level 36 (not hard for a ScM, lol) all 10min/level spells in those schools will last all day.

edit: with circle magic, archmage, earth spell, and CL boosting items, I wouldn't be surprised if ScM could get close to two days without needing to do echoing spell.

edit2: of course sadly many good buffs are transmutation.

Primordial dragonborn incarnate construct half-minotaur warforged.

Ice-dweller dragonborn Primordial Incarnate construct half-minotaur aquatic warforged

That makes you, what, a Giant (dragonblooded, aquatic, living construct)?
Stat mods on that would be, what, +4 con, +2 int?

Rainbow Falls magical location lets you triple the duration of a Transmutation spell once per day. This should directly stack with Extend Spell, for x6, I think.

Depends on the wording, but generally, double in D&D means +100% and triple means +200% so combined that's +300% duration or 4 times as long.

That's for "D&D sizes" like damage, that aren't easily expressed in real-world units. For RL measurements like length, time, and the like, you typically use normal math AFAIK.

I agree. Here is the relevant rules text:

Multiplying

The only possible argument I could see is that while "time" is a real world value, "duration" might not be. Durations are defined using real world values, though. So I don't think this argument holds water. Of course, if the DM is looking to nerf something, interpreting things favorably/strictly is one way to do it, so YMMV.

[Rebel7284]

If that's the case, the multiplication really adds up on the ScM/Circle Magic build.  CL50 X 2 X 2 X 2 = 400 X duration
day/level lasts over a year, hours/level lasts for over 2 weeks, 10 min/level lasts for almost 3 days.  min/lvl lasts over 6 hours.  I guess now we need 1 or two more auto-extending PrCs to get it to truly persistant for min/lvl.  Hmm.

edit: can sudden extend be used with extend spell?
