Kid as DM, great Item ideas

 He's a weapon guy ever since Elden Ring. Has some great ideas. 

1. Ghastly Bow (longbow) that shoots through ppl up to 10 ft behind them. So in theory, lined up perfectly, can hit 3 ppl standing in a line. It's a spirit / ethereal type attack, not regular arrows, eh
1. Super cool idea... theme is cool, tactics are cool/requires effort/not overpowered.
2. Skink Scimitar for ranger. 
1. Lizard themed, with a slightly prehensive tail that magically wraps around your wrist. 
1. Prevents dropping or being disarmed. 
2. Also does a little elemental dmg... maybe 2 more dmg against certain creature types. 
3. Giant Toppler Battle Axe (Great Axe?) for the barbarian
1. Normally is +1 to hit, +2 dmg, but
2. +2 to hit and +2 dmg against Large or bigger creatures. 
1. Sometimes they have to roll to check if prone.
