Stout on bear is a must, gives it a lot of nice damage block.
Treads also works okay on the bear. I prefer treads over phase. Bear deals enough damage per hit and has a ton of ms from rabid (400 base I think, +20% or whatever).
500g --> glove of haste --> 15% as
500g --> boots of speed --> 55 ms
450g --> belt or whatever --> treads! 65ms, 25%as, save a slot.
Stacking gloves is legit
I used to go stout/qb/straight up radiance but I now do a small-items build with wraiths, stout, qb, vlads components (you can put it on either your bear or sylla, use discretion), treads, gloves of haste (on the bear), etc etc.
