Concur with others: get flammifier from the raid shop as a priority, since you don’t know if you’ll ever see it again if not (currently, you won’t).
Jar of Eyes should also be in soulforge today, if you have the spare jewels and diamonds, you might want to consider craft it. This is one of my more commonly used hero mana generation weapons (I have it at +8 across the board so it can synergize with as many teams as possible and generally use a different troop to sustain or create storms) across all my accounts.
Delve weapons and raid/invasion weapons have similar craft costs, but the raid/invasion ones only take 250 gems to unlock while the faction one takes 410 gems. Since you only have two factions on Switch, you could wait the 2 weeks and drop the 410 gems next time, but I still consider soulforge for delve weapons a “less expensive” investment than the event shop, especially if you don’t plan on running the delve event, whereas soulforge for raid/invasion weapons I consider “more expensive”, since the shop offers a better cost/benefit ratio (a new troop not available elsewhere at t2, which is 100 gems anyways, and the weapon for 150 more or 250 gems in total).
