Might help if the goblins (or other creatures movong forward) were numbered, Could post "attack goblin 7" rather than "attack the goblin behind the 3rd bush from the right" Just a thought. Great encounter so far! Chaos rules!!!!
Per your sheet you already have Posion Spray as your Cantrip. Once you pick a Cantrip you can't change it till later in the game if you choose to do so which I believe is a Feat ability. Nomad am I right or wrong?
I assume you mean Guiding Bolt? As a cleric Dok does not have a lightning bolt. Different spell, different class and higher level spell.
You are a bit over 40' from those directly in front of you. Add some distance if you are looking at angles or ones further back.
Guiding bolt - range of 120' Easily within range of anyone you can see except the furthest out archers in the river. FYI - Guiding bolt does 4d6 damage and gives advantage to the next attack on them. It is serious overkill on a normal goblin.
Spiritual weapon - you can have the magical weapon appear anywhere within 60' of your location - so you can get to several targets. Plus, as a bonus action, you can move it 20' per turn and still attack with it. So you could cast it and then move it. You have targets. Remember that once cast it sticks around for 10 rounds. It takes your action on the first turn to cast it, but on subsequent round you can attack (and do the move 20') as a bonus action leaving you your action to do other things like attack normally.
To everyone - I don't normally offer advice (like Guiding bolt is overkill on a goblin) but if you are unsure of anything please do not hesitate to ask. I'm more than happy to let you know the details of how a spell or ability will work.
As noted on the game post - a map will be forthcoming, but might be a bit. You don't necessarily need it for posting so don't wait for it if you know what you want to do.
Also, please remember all of you characters abilities. For example, rogues get sneak attacks and cunning actions. All classes get some special things. Don't forget them. If you have questions about anything, ask.
