You may make something similar to spell "Exura Sio 'Name'", spell with paramethers for example position -> exori mas mort [1342,643,7].
How make this more player friendly (don't write a lot of numbers)?
First -> make this spell in server side.
Second -> Add functionality in client to make hotkey with spell (+ pos) on client side (easy in OTClient), function withcrosshair who cast spell to position where you select tile on map (like rune).
In client side: select hotkey -> function withcrosshair -> select using mouse in map (LMB) or cancel (RMB) -> client count pos -> add string for example 'exori mas mort'..' ['mousePosX()..','..mousePosY()..','..mousePosZ()..']' -> send to server like normal spell.
