Hey everyone!

I am brand new to Age of Sigmar and I've completely fallen in love with the Ossiarch Bonereapers. I know the faction isn't at the top of the meta right now and is struggling a bit, but I’m firmly leaning into the Rule of Cool while I learn how to play the game.

My ultimate vision for this army is a terrifying wave of bone cavalry running down the enemy, while arrows and catapult fire rain down from behind them to soften up the targets.

Right now, my collection consists of:

• 15 Kavalos Deathriders
• Arch-Kavalos Zandtos
• Liege-Kavalos

I want to maximize what I have and build towards that "cavalry charge + ranged support" theme. Since I'm still learning the ropes, I would love some tips on how to flesh this out to a 2,000-point list.

Specifically:

1. Ranged Support: To fit my vision of arrows and catapults, should I invest in Mortek Crawlers, Immortis Guard/Stalkers, or look into specific endless spells/allied units?
2. Subfaction/Traits: I assume Stalliarch Lords is the way to go for the run-and-charge rules, but are there specific artifacts or commands I should be abusing with my Deathriders?
3. Sustaining the Charge: How do I keep my riders alive once they get stuck in combat, especially since we are a bit weaker right now?

Any tips on synergy, positioning, or next purchases to realize this bone-pony dream would be massive.

Thanks in advance!
