I haven't made a suggestion in a while because I've been really busy, and I can't think of a good one right now so you're all getting Bastet.
Bastet will be a low tier stand as it only has one ability, but it will be deadly with proper execution and preptime. With Bastet you will be able to place down an outlet wherever you look within a few blocks. This works like an item frame where it can be placed on any side of a block. You can leave the outlet there and go up to 50 blocks away, but you only get one outlet at a time. You can desummon the placed outlet at anytime
Wherever another player or entity touches that outlet, whether they brush by it or actively click on it, they will hear a small electric buzz and then be afflicted with your ability.
The abilities power will slowly grow over the course of a few minutes.
1st stage: the afflicted player may notice they can pick up metal items from further away
2nd stage: the player can't seem to get there iron armor off or throw away the iron tools in their inventory if you're standing on iron blocks then you are slowed
3rd stage: iron items on the ground or thrown will fly towards the player dealing a little damage and slowing them down the more that add on. Knives have homing, and you are even slower on iron blocks
4th stage: larger items like anvils and minecarts fly at the target dealing substantial damage and slowing the player down significantly, you are immobalized on iron blocks and are pulled onto iron bars.
Being closer to the user will strengthen the stands ability and make it take less time to reach stage 4.
If two or more players are afflicted with Bastets ability they can stick together if they arw both at stage 3. While stuck together their movement is greatly decreased. It is possible to seperate yourselves at stage 3 if you both go seperate direction and sprint out of each others magnet range, but it is impossible at stage 4.
