It has 2 mode BW and COLORS (toggle is framed in red in the screenshot)

With the BW mode "Phoenix Steam_Pencil is a variation on the Pencil theme...
The difference is in "Steam" (a combination of Kuwahara and gaussian blur ) the lower the value used For "Steam" the more subtle is the effect on pencil, the higher the values the more Pencil will be modified and simplified , and result my resemble less the original and become more and more abstract
In between you may found an interesting range where the effect become a sort of hybrid between pencil and sponge

IMAGES ARE MORE CLEAR :"STEAM" to Minimum

Slightly raising "STEAM" values

This was BW, the other mode , COLORS alllows to combine the BW with the original color:
for the examples i used the same setting used for 2nd BW image , but enabling Colors

the first 3 options Value, Lighness ,Luminosity would do it literally, even if each with its logic ( even if apparently similar as concept , results are not equivalent)

This is Lightness

(Value instead will looks darker,and Luminosity a bit different for color rendition )

the following 3 mode Dark-Edges, Vivid-Edges and Vivid Screen were created for the occasion...just see if you like them
(the first 2 are based on gmic edge mode , Vivid Screen is a darker and more saturated variant of Screen )

VIVID SCREEN

VIVID EDGES

The other...well each correspond to a know layer merging mode so to a different mode to combine our BW with the colors from the original...
Sure 18 different merging mode may seems a overkill but on the other hand they assure a lot of power and flexibility here few random examples

PS about the additional colormodes
Dark_Edges=output gmic edges + its dup -merged in Multiply mode
Vivid_edges =output gmic edges + its dup -merged in Grain Merge mode
Vivid Screen=output Screen + its dup - merged in Grain Merge mode
