Have found this to be the case on a few items that are Purple text in database actually....a wee bit strange but I guess someone out there might find the build for it....may be lacking in a lot of other areas mind you as a sacrifice to be able to wear these but none the less they will have a smile knowing they are able to wear these nice fire boots.....
Yup, you are right Claudius in saying if there is a will there is a way however like you said these could only ever be worn by a char that has melee somewhere in its descriptor and considering they are mostly good for a caster type (from looking at the stats) I would say most melee types would rather go for Athena's or Barbarian greaves...
Agreed Claudius the items you have listed look very much like what my Dream/Spirit caster uses (with the exceptions of the staff and helm)....
Have to admit found one half decent staff that is epic level called Blastus Flotas (something like that) which is not bad....and saw that Eye of Osiris staff thingy in the database as a desirable but also realise that may be a wee bit of work trying to find it....have to admit though not a lot else focused towards a fire type caster....

I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhauser gate. All those moments will be lost in time, like tears in rain. Time to die.
