It is off topic, however I'd suggest you try Spidersilk Armor on your concentrating character. It gives advantage on CON saving throws and you only need to roll 10 to pass the concentration ST.
Always glad to get your top tips! I’ve just started a new run trying out a Drow DEX-based OatA paladin. If I can be bothered to carry on that far with my second consecutive paladin run, sounds like the Spidersilk Armour will be perfect for them.
And to be fair to the game, part of my problem with concentration is my own fault for underinvesting in CON because I’m always too tempted by the skill bonuses of the other stats. It generally suits my preferred play style but does mean my characters tend to be overly vulnerable to concentration loss and being put to sleep!
