If you cast enlarge onto a wildshaped bear/deep rothe or the beastmaster companion bear, you go from a large 250-300 kg beast, up to a Gargantuan 5005kg unit. Jumping from a height advantage onto a target will do enormous amounts of damage. When i jumped as a polar bear wildshape onto the ogre guarding the shattered sanctum, i did 14 damage without enlarge. With enlarge, I did 151 damage and it was an easy one shot. Below is a video someone else posted and how I found out about it. No idea if it was reported already. But this is simply game breaking and needs toned way down. If it were to remain, you could win entire encounters with long jump and enlarge buffs casted onto a single druid or ranger companion lol. Id like it to still do meaningful damage, I guess. But certainly not one shot potential!
This honestly seems fine with me. Requires specific units, specific spell combos, and certain areas. D&D is often about comboing spells in odd ways to be more successful than the sum of their parts.
