Hello,
Let me introduce you to Pyrköl, we are launching a line of blast markers and related acessories, they are designed specificaly with Epic in mind, but sme may be usable by BFG and others
I´ll give you a quick rundown on whats available:
The press release on the Blast Markers:
"Pyrkol Launches new Micro Blast Markers.
Designed for the 6mm battlefield, these single and triple Micro Blast Markers represent artillery shelling a battlefield, with a sharp explosion in the center, and the corresponding cloud of debris as a backdrop.
When looking to the battlefield at a glance, there is an instantaneous sense of which units and areas are under fire. And the different shapes and sizes of the marker´s flames provide a great sense of variety on the battlefield.
Use them in numbers and they will not disappoint."

The Damaged Shields marker was designed to mark each shield as it goes down, and removed as they are repaired.

Next the Mechanical Damage Markers to mark damage to war engines and such.
And last but not least generic flames to set everything ablaze.
From the Press Release:
"Pyrkol launches Micro and Mini Flame Markers for 6mm and 15mm wargaming.
The flame markers come in 2 sizes to provide variety on the battlefield.
The set was designed with the objective that even the smaller flames visually pop and are easily visible on even the 6mm battlefield,
the shape and colors were mixed and tweaked again and again untill finally the final effect was achieved."
