5E - Aura Effects Coding

[MrDDT]

Hey All, I have been messing around with using AURAs to do targeting for AoE spells (such as fireball.) So far I have been able to use a spell proxy, drop an effect on it, and use the SAVEA function and the spells are targeting and working like a charm. The only thing I am trying to work through is how to make the aura then vanish on use. I have tried the expend on use, expend on roll, and changing of states, but I'm not sure I am using the correct verbiage.
For an example, here is the code I have used for Arms of Hadar - this obviously gets dropped directly on the pc instead of a spell token, but the same could be used on a spell proxy for something like fireball.

AURA: 10 all; Arms of Hadar; IF: FACTION (!none); SAVEA: [SDC] STR (M); SAVEDMG: 2d6 necrotic

Fireball would just be:
AURA: 20 all; Fireball; IF: FACTION (!none); SAVEA: [SDC] DEX (M)(H); SAVEDMG: 8d6 fire

anyway, right now its easy and the character just has to remove the effect right after they cast it, but I am just wondering if there is a way to automate that.

Thanks!

There is no way to really code this for a proxy token.
You can do it for something that needs to make a check but using a proxy token that has no effects or rolls or checks happening, no way to turn it off without a turn change.

The way that FG has set this up to do, is if someone is casting a fireball (or any spell like that), you target all the creatures in the area and roll the save then damage.

If this was an ongoing effect like lets say a mine/trap, was in the area and you walked into that area it would blow up. You would want to leave the aura there, or if it was a 1 time use mine/trap, you would remove the trap after it blew up.

Thanks, I kind of figured that was the case, but I figured I'd ask. This is just removing the forced targeting of each creature, then it rolls the save and damage. Kind of fun to watch the wizard just drop a token then click one button. (now he just has to remove one effect, which is well worth it. Now, there is still the limitation that the aura goes through walls, so if someone is on the other side they are being automatically targeted, despite LOS. In those cases we will either target the same old way, or I'll refund the wounds.

Thanks again!

Have you tried using generic actions utilizing the extra extension in it called generic action layers?

It will do sort of what you looking for in a totally different way.

I created 2024s Assimar Auras:


Necrotic Shroud:

Necrotic Shroud;LIGHT: 10/10 331133; AURA: 10, foe, once; IF: FACTION(enemy, !self); Necrotic Shroud AOE; SAVEA: [SDCWIS] CHA (M) (R); Frightened

the problem is, how can i set it up to remove the Frightened at the end of the source turn?


I also created Inner Radiance ,for those who wants it:

Inner Radiance;LIGHT: 10/10 FFFFFF; AURA: 10, all; IF: FACTION(!self); Inner Radiance AOE; SDMGOE: [PRF] radiant

There is a way to accomplish this through the use of custom NPCs. I do effects that I drop on NPCs in the combat tracker for spells such as Healing Spirit and Guardian of Faith.

I haven't attempted Arms of Hadar, but I am about to set one up for Evard's Black Tentacles since its a favorite spell of one of my players.

I also set up NPCs for spells like Spiritual Hammer. The players love that one.

The code you made for Necrotic Shroud I believe is wrong.

1) It's instant check and not an AURA effect, it's just like if a fireball went off you would target all the creatures (enemies in this case) in the area 10ft around you and do a save.
2) You also have it set as a SDCWIS which means Spell DC based on Wisdom as the modifier to check, however it's both a CHA SAVE and a CHA modifier. So, it would be 8+PRF+CHA.
This is not a good one to do an AURA on IMO.
However, to answer your question, you would create a custom effect named whatever you want that is not matching another custom effect nor a condition. So, something like "Necrotic Shrouded; Frightened" then set the duration there and the tag on it would be SRE = Remove End Source Turn.

Wondering if I could get some help automating the Bulezau's Rotting Presence feature. The entry is from Mord's Tome of Foes and does the following:

Rotting Presence. When any creature that isn't a demon starts its turn within 30 feet of the bulezau, that creature must succeed on a DC 13 Constitution saving throw or take 3 (1d6) necrotic damage.

There is an effect for it in the 5e automatic effects module but it's not an aura. Thanks!

Edit: I figured it out. Here it is for anyone.

ROTTING PRESENCE; IFT: !TYPE(demon); AURA: 30; SAVES: 13 CON; SAVEDMG: 1d6 necrotic

Any ideas on why this isn't rolling any saves? I've been staring at it for 45 minutes and I can't figure out why nothing is rolling...like at all. If I remove the faction check, the SAVEA doesn't appear in the effects panel of the CT.

Zone of Truth; AURA: 15 all; Zone of Truth; IF: FACTION(!self); SAVEA: [SDC] CHR (D); SAVES: [SDC] CHR (D); SAVEADD: Truth

A charisma save is CHA, not CHR. And I think you also need BCE/BCEG for SAVEA.

Few things I wanted to point out.

1) Getting it to work.
Your coding should work if you change CHR to CHA and you need Better Combat Effect Gold ext.

2) This does not go on the caster or creature, it goes on an AREA effected, so you need to use an proxy token, we call these "Objects" NPCs. If you need help setting this up let me know.

3) This is how I think you want it to work.

Use from the Caster's Action Tab to an OBJECT NPC to denote an AREA effected.

Zone of Truth; AURA: 15 all, once; AoE Zone of Truth; IF: !CUSTOM(Object); IF: !CUSTOM(Truth); SAVEA: [SDC] CHA (M); SAVEADD: Truth; SAVES: [SDC] CHA (M)
