I'm planning on doing some scouting and wanted to know if I can tell my DM that I always have BladeWard up until something happens (either I'm surprised or see something - basically when initiative needs to be rolled).
Casting Time: 1 action
Components: V, S
Duration: 1 round
You extend your hand and trace a sigil of warding in the air. Until the end of your next turn, you have resistance against bludgeoning, piercing, and slashing damage dealt by weapon attacks.
Will this impact my movement? I do plan on doing this from the air (aerial recon). I'm a level 3 rogue so I have a bonus move action if that makes a difference.
I suppose if I take an action to cast the cantrip I may not have an action to make an active perception check, but I should still have a passive check for hidden things.
Any support RAW for or against this would be great.
