Variant Human War Caster

As a follow-up to last week’s post comparing the War Caster and Resilient (CON) feats, let’s take a look at how the numbers shake out if you’re playing a Variant Human or in a campaign where your DM lets you have a free feat at level 1.

The Lesson

Remember the lesson from last week:

Need a feat faster?
Go get War Caster.
Wait for Resilient.

This should tell you that if you get a feat at level 1, War Caster is going to be the most effective choice. It will give you a stronger benefit while you level up your spellcasting ability score. Once you hit the level 12 ASI and you’re entering the part of the game where the proficiency bonus is going to provide a bigger benefit than advantage, you can take Resilient and double up the effects. However, War Caster is going to provide a larger benefit against most DCs until you get there.


Assumption 1. The character gets a feat at level 1.

Assumption 2. The variant human invests their floating +1 ASIs in their primary spellcasting score and their Constitution (CON) score.

Assumption 3. You’re not playing a Sorcerer or getting CON save proficiency elsewhere (such as from a Fighter dip). If you already have proficiency in CON saves, save Resilient for an ability score other than CON.

The Numbers

Level 1

At level 1, War Caster is better. This is especially true since you’d have to take lethal damage to set some of the higher concentration DCs.

Vuman War Caster - level 1 CON 16

For this chart, we’re assuming that you maxed your spellcasting score and CON if you’re playing a Vuman spellcaster. Assuming a higher CON score is generally more favorable to War Caster. As your CON score decreases, Resilient becomes a stronger option.

Vuman War Caster - level 1 CON 14

These numbers hold out consistent through level 4, when you have the chance to take your first real ASI.

Leveling Up

War Caster continues to excel through early tiers of play. Since odds at level 1 are going to continue through level 4, we’ll examine the shifts from the proficiency bonus increase at levels 5 and 9.

After Maxing Spellcasting Score

Once you’ve maxed your spellcasting score, your next ASI (at level 12) is the perfect time to pick up the Resilient feat. The odds when you have both feats is represented by the green dotted line at the top.

Vuman War Caster - level 12 CON 16

While War Caster is still a bit ahead against low DCs at level 12, Resilient kicks ahead the next time you level up and get the proficiency bonus increase.

Vuman War Caster - level 13 CON 16

Keep in mind that as you reach these higher levels, damage totals also tend to increase, making the DCs on the right side of the chart more relevant.

Odd Constitution Score

If you have invested your ability scores such that you have an odd CON score, Resilient becomes a stronger choice at earlier levels.


At lot of what makes a feat great is situational. If the fringe benefits of these feats beyond their concentration benefits are important to your character, do what’s best for you. These numbers should allow you to appropriately weigh the value of the concentration benefits among the rest.

If concentration is what you value most, then you should strongly consider War Caster for your level 1 feat. Then, take Resilient (CON) at level 12 after you’ve maxed your spellcasting score.

This assumes you don’t have other intentions for your feats. If you’re limited in the number of feats you can select and plan on taking your character to level 20, it might be worth it to you to sacrifice the effectiveness of War Caster from levels 1-12 so that your character has better odds of maintaining concentration at level 13+. War Caster doesn’t keep being better because you took it early; it just carries you though those early levels better than Resilient.
