d&d 5e ranger idea:

lair-master:

• roll a gnome beastmaster and get a giant frog companion
• giant frogs can swallow small creatures, like gnomes
• train it to swallow you without harming you
• construct a gnomish clockwork periscope and snorkel
• climb into your giant frog and hide there all day every day
• in combat, pop out and fire arrows then pop back in
• enemies look where arrows came from but it’s just a frog
• for bonus points, use minor illusion or ventriloquism to speak through it so everyone thinks you’re a giant awakened frog
