Hi,
This is now a team composition available for solo play as opposed to the 8 human players requirement before - thanks to the "of the Dervish" mod introduced during the 20th anniversary update. Details below!
I've tried similar arrangements before, but this one is the most polished version I could make. Except for Derv heroes you must mod your Spears with an "of the Dervish" mod to guarantee VoS uptime (which is 11 seconds thanks to the mod + Extend Enchantments). AI doesn't prioritize skills but it does a decent enough job to refresh Extend Enchants + VoS. Your healing should cover the downtime.
The upside is that your party is basically immune to all incoming spells, meaning most of the hate you'll receive is slashed significantly. What can bother you is martial enemies (especially Dervishes in HM) and you are equipped to deal with them using YAW and Throw Dirt. Condition removal is handled via Recovery.
I tried to include all professions that can play in this composition even though my original intention was to make it 4 Paragons and 3 rangers + Xandra. Then I realized that getting Thackeray and the third ranger hero can be a drag so I opted for this composition instead.
Hope you enjoy.
Edit: Overhauled the entire build/first post thanks to the "of the Dervish" mod introduced during the 20th anniversary.
