FYI, if i am reading it correctly Holliday, skill 1 does not work properly:

GeSHi (eventscripts):
"skill1_setting"    "es_xset wcs_multiplier 0.7|es_xset wcs_multiplier 1.3|es_xset wcs_multiplier 1.9|es_xset wcs_multiplier 2.4"
    "racealias_rdn1"    "es es_xsetinfo wcs_magnitude event_var(dmg_health);es_xmath wcs_magnitude float;es_xmath wcs_magnitude * 3.0;es es_xmath wcs_magnitude * server_var(wcs_multiplier);es est_RoundDecimal wcs_magnitude server_var(wcs_magnitude) 0;es wcs_explode event_var(attacker) event_var(userid) server_var(wcs_magnitude) 50;wcs_getlanguage wcs_lng wcs_lng_r_critgren;es es_xtell event_var(userid) #multi server_var(wcs_lng);es es_xtell event_var(attacker) #multi server_var(wcs_lng)"
    "skill1_cmd"        "es es_xif (event_var(weapon) in server_var(wcs_wpn_grenades)) then est_isalive wcs_alive event_var(userid);es es_xif (event_var(weapon) in server_var(wcs_wpn_grenades)) then es_xif (server_var(wcs_alive) = 1) then racealias_rdn1"
    "skill1_sfx"        "es es_xif (server_var(wcs_dice) <= server_var(wcs_chance)) then es_xgetplayerlocation wcs_x1 wcs_y1 wcs_z1 event_var(userid);es es_xif (server_var(wcs_dice) <= server_var(wcs_chance)) then est_effect 10 #a 0 sprites/lgtning.vmt server_var(wcs_x1) server_var(wcs_y1) server_var(wcs_z1) 20 5000 2 100 300 1.8 175 175 255 255 1"

You have es es_xif (server_var(wcs_dice) <= server_var(wcs_chance)) in there, but no "es_xsetinfo wcs_chance", just a multiplier.  I was wondering why the damn effect was going off every shot.
