An update!
We had the first part of this fight last night... It went good!
Managed to split the orcs up with some distraction tactics. Got the fight into a wooded copse - which was the most cover we could get - thought carefully about the compound, but we'd have had an extra few hundred orc archers to deal with, so left it...
Took on two of them - a druid and an order of the bow initiate.
Managed to use a number of things from here.
Telekinisis to 'help' them dismount was fun - worked like a charm and has a great range - interesting suprise for the GM as well.
Searing light was great value - managed to inflict some very hefty damage on them - Cleric touch attack + no save = The Nasty!
Neutralise Poison saw off some potentially nasty as well - Wyvern stingers in particular.
On the downside, our Paladin had some bad luck. Charging 'mega smite' failed to connect. Followed closely by an introduction to 'Close Combat Rapid Shot' with an unholy bow, then a lightning storm/flame strike cocktail... Ouchy! At least there was enough left to selotape back together...
Also undead that heal from fire damage are fun! Ate a couple of fireballs before we worked that out!
Next week, we've got some of the other 4 to deal with. Our mage went for
Summon VI, so Elemental party time!
Wall of force should be making a guest appearance. I took
Plane Shift, but I think using it offensively is getting into new and dangerous territory... probably save it for the running away
Anyway, thanks a lot for the help - it's been a lifesaver! I'll be back to let you know how the rest of it went...
