As a fairly new player who only owns the base game, it seems as though the Runemaster's Arcane Bolt is very strong for a starting weapon. Whereas most class's weapons have a clearly superior replacement in the Act 1 deck, Bolt is strong enough to last all the way through the Interlude. Our Runemaster pulled an Immolation rune from the shop deck yesterday and wasn't convinced that it was better than his Bolt. Sure, it gives you more damage, but surges are so important to the Runemaster that he declined to buy it.
Are we evaluating the weapons incorrectly, or is Arcane Bolt really that strong?
