There is no context needed for Wand of Warding or Bless. Wand of Warding would always target the last targeted ward (or nothing). Bless would always default to yourself.

You never want Wand of Warding targeting an enemy. Targeting an enemy sometimes plants a ward at their feet where they immediately melee it (unless they are targeting you), but often it does nothing and wastes the charge.

It would be desirable to force the player to select a location (and perhaps actually prevent them from targeting enemies since that behavior is so inconsistent). And once a location is selected, the best next step is to target the same ward again. It’s the thing you will do literally hundreds of times in Wand of Warding run, yet the game doesn’t help you do that. Instead, you are forced to manually target it over and over and over, leading to mistaps and wasted charges.

What I want to avoid is the player tapping an item and either having to pause to see what it is auto-targeting.

That’s exactly what you have do today! Bless targets an enemy with a purely beneficial spell. Wand of Warding targets an enemy and does literally nothing. You are forced to manually target these effects every single time. They auto target the wrong thing every time.

You say you don’t want players reflexively making mistakes, but I started this conversation explaining how I reflexively made a mistake and casted Bless on an enemy. That’s exactly what I’m trying to avoid.

You don’t have to change anything else. If you literally only changed Bless and Wand of Warding, I’d be happy, and so would every other player. You can’t tell me that would confuse players or cause them to make reflexive mistakes. (They are not meant to target enemies!) Maybe it turns out that those are the only two spells or items that can be easily changed. That’d be fine. The game would be much better even with just those two changes.
