It was in the death recap. Use Spear shards to help beat them.
A little bit of background info ..
I'm doing the Ripple Effect quest in Glenumbra. It's a lvl 10 quest. I've got to retrieve a few Blades of Alessian Generals. My Templar is lvl 12, wearing 5/1/1 heavy/medium/light, brandishing a two handed weapon. That's what the character creation screen clearly recommended, and I like the look/feel of this combination (I'm aware it's less than optimal). I have one class ability from each stream equipped. I've used them religiously from creation.
I start by clearing out the wraiths. This builds my ult to respectable levels (500% plus). There's a group of three infantry that I need to take out to get the first part and move onto the next one, so I decide to try a group of two first up. So I select two that are isolated from the rest and go into battle. Now I don't know where the third magically appeared from, but I died rather quick. I've been doing just fine up to this point and don't actually consider death to be an issue.
But then I get the newly introduced death recap screen. And I'm like "WTF?"
Use Spear Shards it said.
Turns out that Spear Shards required lvl 30 Aedric Spear. Mine is at lvl 16. So the creators of the game recommend I use an ability I won't unlock for another 14 lvl's to beat this lot, despite being two lvl's higher than the quest they recommend using it in?
Something is not making sense here.
Yes, I'm solo, and there's no other player activity in the area.
