So, you're driving Keyla today...

Luckily, in terms of combat mechanics, Fighters are pretty straight forward! Here you'll find any handy notes you'll need for the session, general combat info and tips, and a flowchart that, generally, outlines how to approach combat with Keyla.

Special Notes for August 2nd session

Keyla's main goal right now is to show others than she can be relied upon and to build trust with the party. Whatever muscle or lockpicking or conversation needs to be had, she'll gladly volunteer if she seems capable.

She is not so magically inclined, so this primordia melding business is a bit out of her comfort zone, but she's here to cooperate. She would be interested to see if there was any paperwork/signs/objects that might be related to Consecution, Crystalloy, or stalking and banditry. I (the player) don't have any indication that this is information that would likely be found in a place like Deastock, but you never know! At this point Keyla is keeping more of a relaxed approach on this, and isn't necessarily scrouging through everything to find any information on these topics.

Things To Note

Vex: If you hit a creature with a weapon that has the Vex propety (Crystalloy Boomeraxe), your next attack against the same creature will have advantage, until the end of your next turn.
Nick: Short version - if a weapon has the Light AND Nick property, Keyla gets an extra attack with that weapon as part of her Attack Action. E.g. she can attack with Boomeraxe AND Scimitar on the same Attack Action.
Thieves' Tools: Keyla is able to produce Thieves' Tools from her Crystalloy arm. Roll 2d20e + proficiency bonus when rolling to use. These shatter on a critical fail, and need to be regrown after a long rest.
Earring of Message: Pretty good for medium distance communication. Can whisper a message to someone I can see in 120ft. Check Inventory for more details.
Tactical Mind: In and out of combat, Keyla can spend Second Wind resources to potentially succeed. See Features & Traits > Class Features > Tactical Mind.

TLDR; Combat

Action: Attack with Crystalloy Boomeraxe first, then Scimitar. This gives advantage on Scimitar if it hits. Use Savage Attacker feature to potentially roll higher damage on a low damage roll, once per turn.

Protip: Crystalloy Boomeraxe can be thrown from range OR used melee.

Bonus Action: Mostly for Second Wind if her health is looking iffy.
Free Action: If Crystalloy Boomeraxe shatters, Free Action can be used to regrow a new one, so long as there are charges available (tracked on Inventory page). Action Surge is also available.
Reaction: Hellish Rebuke can be used to inflict fire damage if Keyla is hit.
Other: She currently has Nectroic Primordia I equipped in her Item slot. On failing an ability check, see if makes sense to use Tactical Mind to potentially succeed.

Crystalloy Boomeraxe Macro

For (hopefully) ease of use, there is a Macro available for rolling to hit with the Crystalloy Boomeraxe. It will prompt for Advantage/Emphasis/Disadvantage, auto-roll damage when not a critical failure, and call out the weapon shattering on a critical fail.

You can add this Macro to your toolbar by opening Keyla's character sheet, clicking Advanced Tools, and toggling Show on macro bar for the CrystalloyBoomeraxe macro. This should make a button appear on the bottom of Roll20, below where user portraits and names are displayed.

Disclaimer: Knowing D&D, you will probably run into a scenario where this flowchart doesn't help! It is meant as a generic guide to combat that should work well enough for most battle situations. Use your best judgement, I believe in you!
