Going to try and do a subpar job answering these.
Options not mentioned. Buff her a tad. Get her take on what the character is. Ambush attacker, get into the midst of combat and out survive the opposition…
But combat type and style is a factor in what she should do, and if she is playing a glass cannon, survivability against multiple opponents is small.
I’m assuming she is not playing a dwarven defender with all points in con, and a couple of shields and armor. Then the path is easy. Hit till low, then take a recovery action and hit till low and take a recovery action, rinse and repeat till there is no one attacking anymore.
Now onto Analysis Paralysis, what’s her characters perfected attacking situation? What’s her characters default attack, what is her characters default retreat, what is her characters preferred attack, what is needed to set that attack up?
Not sure what to do, default attack or retreat. Oh if I can get those two lined up…I’ll take them down, she moves to line them up and attacks.
Perfect attacking situation is from dark cover, she seeks cover, attacks and finds cover again.
Now if she made a glass cannon, and you are sending her into a meat grinder with no one to help her…change the story narrative.
Glass cannons are just that, they hit really hard, but can’t take much. So the familiar in the form of a dog, or bear who acts just like a dwarven defender in combat, starts to look really appealing. She controls both adding to analysis paralysis.
Defender does attack, recover attack, and one or two other things, but that’s the defaults, she does massive damage run back massive damage run back…until they line up…and does a devastating attack.
Now to fit it all in, she nearly escaped some trial, she runs into the woods and waits for searchers…none come and she is exhausted, falling asleep under some leaves she wakes up to someone licking her face. How does she befriend the curious beast?
Let us know.
Default moves if she doesn’t know what’s best. Not the most devastating.
Attack run away, attack run away…just keep on running if there is an opening.
Why are you sending your wife into a meat grinder?
Are you playing zombie apocalypse?
You having personal power dynamic issues?
You don’t have her as a one woman army against a bunch of monsters who have her brother or something…that’s just cruel. You probably have her playing a complex magic wielding sword mage or something stupidly complex and useless without the right gear on top of that…you are a terrible terrible human being…j/k but if you are doing all that simplify it a tad.
In reality what you are doing is hard. Balancing a one character adventure for an inexperienced player with no training wheels…and someone who you have history with.
It’s hard, your job is to make it fun, not fit the story. Later you work on narrative. But don’t get her off to the wrong foot that it’s only about combat. Be a dork, do silly accents and make sure she has fun. Also one on one games, offer a ton of collaboration, you both tell the story. Take advantage of that. Let this be a learning experience for you.
