hidus laughter can stop an enemy in there tracks at 20th level or 1st
1. Assuming the creature fails it's save. 2. Assuming you have any slots left. If you're burning through slots using shield, you probably don't have any left after 3.5 encounters. 3. You're assuming this isn't a legendary creature, which is a poor assumption at those CRs. They get to auto save against things like this.
shield can negate a hit at 20th level or 1st
Okay. So you're burning through your low level slots during those first 3.5 encounters as well.
charm person can turn an encounter at 1st or 20th level...
Charm Person is weak sauce if the DM plays it properly. At best, you can, if you get lucky and it misses its save, force a draw where the party gets no exp or treasure. Um, yay. And that's if you have any slots left after all the shield spells you cast.
blur grants disadvantage on attacks. that is a 2nd level spell
Cool. Another spell you're burning through in the first 3.5 fights. This is not a reaction like shield, so you've used 40% of your remaining slots(including 1 3rd level slot) defensively, limiting the number of attempts at shield, charm and tashas's.
counterspell dispel haste fireball lightningbolt are all3rd level spells and all helpful the entire campaign
You have 3 third level slots. If you are using counterspell, you are likely out of the remaining 2 3rd level slots in the first 3.5 fights.
you are NEVER a subpar fighter reread what I wrote. the damn SoS 1st level spell can be used at will at 20th level. (17th I think)
With all the nova you are doing, you will have your signature spells and that's it by the end of 4 fights. So 1 first, 1 second, and cantrips. Hoping and praying that a CR 20+ creature fails a save, because every round it succeeds is a round that you are useless in the fight.
lol SO you just assume those umpteen high level spells are cast first? what if the first round of every encounter you use a cantrip while you plan what big shanangins spell you will end the encounter with> the fact that 5% of the time you have to defualt to doing half the damage of the fighter is meaningless when 80% of the time you can be doing better (other 15% is about equal)
If the first round you use a cantrip, you've fallen behind the fighter that fight. 5e isn't 1e, 2e and 3e. There really are not a lot of encounter ending spells, and saves at that level are likely to be made, not missed. Most of the encounter turning spells will just mean 1 round of you being useless, since there's little to no effect if a save is made.
damage causeing spells are on average slightly worse at 1st and 2nd level then cantrips... but you can load up with charm, laughter, blur, and shield
