This would be great just unsure how complex the programming would be

Could also make it that you could use the ammies between each other to put the charges together

i'd be happy if it didn't randomly not pop up the text box or interrupt TP and lose a charge to be honest.

This was supposed to be fixed.

If you read into rsc mechanics the D ammy is linked to your character not the amulet it self. I would not have a problem with your suggestion though except the limited bank space, having a 1, 2 3, 4 ammy floating around :\

This has been fixed a while ago.

Also its 4 times teleport per ammy.
Even if u trade it over to another account.

But maybe could add 'Examine' and it tells 'Has (x) Charges Left' would be something good.
This would not be a thing to consider as a prior at the moment tho.

A tad incorrect, your character has 4 charges and on the 4th charge the ammy used with become uncharged. If you trade it to another person, it will have what ever charges that account has.
