How to increase spell attack rolls?

[MrQun]

Got this game a few weeks ago, and have learnt a fair bit about the mechanics. Even so, there are many tings that that still alludes me, the hit chance and saving throws for spells/ abilities is among them.

Take the spell Hold Person for example: This spell states that the target needs to pass a wisdom skill check in order to resist the effect. So does that mean that if the castor's wisdom is higher then the targets, then the spell is more likely to succeed? If not, is there a way to increase it's success rate.

But the real problem with Hold Person is the spell's attack roll. I don't think that I've ever had an attack roll that was over 60% Is there a way to increase spell attack rolls?

It seems to me that spells need to pass two difficulty checks, one to actually land on the target and another to apply the effect. I can't tell you how many times a spell has missed a target or if it did hit, the target successfully saved against it.

I love this game, but it is truly frustrating some times.

In DnD there are two different ways in which spells are resolved.
One is that the target has to succeed a saving throw agains 8 + spellcasting modifier + level proficiency bonus to avoid the effects (or halve the damage).

The other is a spell attack, which works like a regular attack, but you use your spellcasting modifier instead of strenght.

If you check the discription of the spells, you'll see which way it is. If you pump up your spellcasting modifier, targets have it harder to resist your spells.

no, each class has a specific casting stat:

intellect: fighter(eld knight) rogue(arcane trickster), wizard
wisdom:cleric, druid, ranger
charisma:bard, paladin, sorc and warlock.

if you want a higher chance, you level that stat, some items (commonly staffs, you'll find them around) will add a higher DC (meaning the enemy has to roll better to win) which is the same as getting more in that score.

another thing to consider: some enemies simply have better saving throws then others, so its something you have to decide to risk.

the formula for a DC for a spell is 8+spellcasting mod(this is int/wis/cha, every 2 points above 10 is a +1)+prof bonus+(item bonus).

so at lvl 1 with 17 in int, you'd have 8+3+2, or a dc15, meaning the enemy has to roll a 15 or above to not get hit(or get hit less)

You can't increase Spell Attack until the Underdark.

There's no attack roll for the spell. The % chance you're seeing is the % chance that the spell will beat their WIS saving throw. This is calculated by them rolling a d20 + their WIS save against 8 + proficiency bonus + casting modifier (INT/CHA/WIS, depending on your class).

Certain things you can do to bump up the success rate include.

1.) Targetting people with low WIS

2.) Giving people disadvantage on WIS saves via spells like Bestow Curse.

3.) Boosting your casting modifier with spells, potions or equipment.

Check this
https://steamcommunity.com/sharedfiles/filedetails/?id=3107682627
it contains the details you want to know about hit chances and such

in short for the specific example of yours

on the hand spell casting modifier e.g. Wizards use INT Sorcerers use CHA
since that will be considered in the attack roll the higher the better (maximum +5)

on the other hand as you correctly deducted, the saving throw of the target
best to apply something like Hex beforehand to reduce / put a disadvantage on the target's saving throw

You can also use right click and examine a target to see their stats and determine whether they are strong or weak against something.

Feel free to ask for details ~

Spell Attack= Proficiency Bonus+Caster Modifier+any misc Modifiers
Spell Save DC= 8+Proficiency Bonus+Caster Modifier+any misc Modifiers
typically from lv.1 to lv.3, you'll have a Spell Attack of +5 and a Spell Save DC of 13
lv.4 most people increase their caster attribute to 18-19 giving them a Spell Attack of +6 and Spell Save DC of 14. then at lv.5 your Spell Attack goes up to +7 and Spell Save DC to 15. at lv.8 you're caster attribute is generally raised to 20 giving you a Spell Attack of +8 and Spell Save DC of 16, finally starting at lv.9 before any gear, your Spell Attack with a 20 in your caster attribute is +9 and your Spell Save DC is 17. with certain pieces of gear, you can easily get another +3 or more to both.
