@Zed Clampet Getting more levels is always fun since it opens up completely new ways to play the game, but I also want to emphasize that using the environment and your utilities to your advantage is more important. In a way, being underleveled is actually a good way to learn the game mechanics better, since you have to use different strategies (which there are an enormous amount of) to beat the fight and doing so without relying on powerful spells.
Obviously, this is easier said than done on first plays, but I just wanted to share that since I know that in BG3 you don't even need to be over lvl 1 to beat the game. That might seem completely ludicrous, but it's BG3.
Some funny stuff you can do and more to show the depth of BG3:
You can make a character that kills people by touching them. You can make a character that throws items with such force it rips the fabrics of space. You can make a character that can slap foes so hard they smell sausages. You can make a character so stealthy, you can stab, stab, stab, stab, stab and then stab yourself into victory. You can make a character into a literal monster with giant claws. You can make a character so small, you can visit places you really would not want to. You can make a character so radiant, even the mighty Zeus would think you were cool. You can make a character so icky, you basically smell like shait all the time. You can make a character that make animals want to call PETA on you. You can make a character that can leap so far, you'd finish the game before you say "Larian, wtf!." You can make a character so charming even the local bard wants to wed you. You can make a character that makes a new character! You can make a character that watches another character do live surgery on yourself and then be happy about it afterwards. You can also make a character that makes other people do live surgery with somewhat mixed results.
