Stuck on last few, as there are several possible answers for each which all link in to each other I'm getting frustrated.
6a Glint (7) ?????E? (could be Glimmer or Shimmer)
9a Freeze (3) ??? (could be ICE, SET or FIX)
1d Endurance (5) ????? (could be ?L??? or ?H??? )
2d Sprite (3) (could be IMP or ELF, probably IMP to fit in with glimmer or shimmer )
Hope I haven't made this too confusing, all help appreciated, Thank You
